®HI5760
10-Bit, 125/60MSPS, High Speed D/A
Converter
The HI5760 is a 10-bit, 125MSPS, high speed, low power,
D/A converter which is implemented in an advanced CMOS
process. Operating from a single +3V to +5V supply, the
converter provides 20mA of full scale output current and
includes edge-triggered CMOS input data latches. Low glitch
energy and excellent frequency domain performance are
achieved using a segmented current source architecture.
For an equivalent performance dual version, see the HI5728.
This device complements the HI5X60 family of high speed
converters offered by Intersil, which includes 8, 10 , 12, and
14-bit devices.

NOTES:
2. Gain Error measured as the error in the ratio between the full scale output current and the current through RSET (typically 625µA). Ideally the
ratio should be 31.969.
3. Parameter guaranteed by design or characterization and not production tested.
4. Spectral measurements made with differential coupled transformer.
5. Measured with the clock at 50MSPS and the output frequency at 1MHz.
6. Measured with the clock at 100MSPS and the output frequency at 40MHz.
7. See ‘Definition of Specifications’.
8. It is recommended that the output current be reduced to 12mA or less to maintain optimum performance for operation below 3V. DVDD and AVDD
do not have to be equal.
9. Measured with the clock at 60MSPS and the output frequency at 10MHz.

Definition of Specifications
Integral Linearity Error, INL, is the measure of the worst
case point that deviates from a best fit straight line of data
values along the transfer curve.
Differential Linearity Error, DNL, is the measure of the
step size output deviation from code to code. Ideally the step
size should be 1 LSB. A DNL specification of 1 LSB or less
guarantees monotonicity.
Output Settlin g Ti me , is the time required for the output
voltage to settle to within a specified erro r band measured
from the beginning of the output transition. In the case of the
HI5760, the measurement was done by switching from code
0 to 256, or quarter scale. Termination impedance was 25
due to the parallel resistance of the output 50 and the
oscilloscope’s 50 input. This also aids the ability to resolve
the specified error band without overdriving the oscilloscope.
Singlet Glitch Area, is the switching transient appearing on
the output during a code transition . It is measured as the
area under the overshoot po rtion of the curve and is
expressed as a Volt-Time specification.
Full Scale Gain Error, is the error from an ideal ratio of 32
between the output current and the full scale ad just current
(through RSET).
Full Scale Gain Drift, is measured by setting the data inputs
to all ones and measuring the output voltage through a
known resistance as the temperature is varied from TMIN to
TMAX. It is defined as the maximum deviation from the value
measured at room temperature to the value measured at
either TMIN or TMAX. The units are ppm of FSR (full scale
range) per degree C.
Total Harmonic Distortion, THD, is the ratio of the DAC
output fundamental to the RMS sum of the first five
harmonics.
Spurious Free Dynamic Range, SFDR, is the amplitude
difference from the fundamental to the largest harmonica lly or
non-harmonically related spur within th e speci fied wi ndow.
Output Voltage Compliance Ran ge, is the voltage limit
imposed on the output. The output impe dance load should
be chosen such that the voltage devel oped does not violate
the compliance range.
Offset Error, is measured by setting the data inputs to all
zeros and measuring the output voltage through a known
resistance. Offset error is defined as the maximum deviation
of the output current from a value of 0mA.
Offset Drift, is measured by setting the data inputs to all
zeros and measuring the output voltage through a known
resistance as the temperature is varied from TMIN to TMAX.
It is defined as the maxi mu m deviation from the value
measured at room temperature to the value measured at
either TMIN or TMAX. The units are ppm of FSR (full scale
range) per degree C.
Power Supply Rejection, is measured using a single power
supply. Its nominal +5V is varied ±10% and the change in
the DAC full scale output is noted.
Reference Input Multiplying Bandwidth, is defined as the
3dB bandwidth of the voltage reference input. It is measured
by using a sinusoidal waveform as the external reference
with the digital inputs set to all 1s. The frequency is
increased until the amplitude of the output waveform is
0.707 of its original value.
Internal Reference Voltage Drift, is defined as the
maximum deviation from the value measured at room
temperature to the value measured at either Tmin or Tmax.
The units are ppm per degree C.
Detailed Description
The HI5760 is a 10-bit, current out, CMOS, digital to analog
converter. Its maximum update rate is 125MSPS and can be
powered by either single or dual power supplies in the
recommended range of +3V to +5V. It consumes less than
165mW of power when using a +5V supply with the data
switching at 100MSPS. The architecture is based on a
segmented current source arrangement that reduces glitch
by reducing the amount of current switching at any one time.
The five MSBs are represented by 31 major current sources
of equivalent current. The five LSBs are comprised of binary
weighted current sources. Consider an input waveform to
the converter which is ramped through all the codes from 0
to 1023. The five LSB current sources would be gin to count
up. When they reached the all high state (decimal value of
31) and needed to count to the next code, they would all turn
off and the first major current source would turn on. To
continue counting upward, t he 5 LSBs would count up
another 31 codes, and then the next major curren t source
would turn on and the five LSBs would all turn off. The
process of the single, equivalent, major current source
turning on and the five LSBs turning off each time the
converter reaches another 31 codes greatly reduce s the
glitch at any one switching point. In previous architectures
that contained all binary weighted current sources or a
binary weighted resistor ladder, the converter might have a
substantially larger amount of current turning on and off at
certain, worst-case transition points such as mid-scale and
quarter scale transitions. By greatly redu cing the amount of
current switching at certain ‘major’ transitions, the overall
glitch of the converter is dramatically reduced, improving
settling times and transient problems.

Digital Inputs and Termination
The HI5760 digital inputs are guaran teed to CMOS levels.
However, TTL compatibility can be achieved by lowering the
supply voltage to 3V due to the digital threshold of the input
buffer being approximately half of the supply voltage. The
internal register is updated on the rising edge of the clock.
To minimize reflections, proper termination should be
implemented. If the lines driving the clock and the digital
inputs are 50 lines, then 50 termination resistors should
be placed as close to the converter inputs as possible to the
digital ground plane (if separate groun ds are used).
Ground Plane(s)
If separate digital and analog grou nd planes are used, then
all of the digital func tions of the device and their
corresponding components should be over the digital ground
plane and terminated to the digital ground plane. The same
is true for the analog components and the analog ground
plane. The converter will function properly with a single
ground plane, as the Evaluation Board is configured in this
matter. Refer to the Application Note on the HI5760
Evaluation Board for further discussion of the ground
plane(s) upon availability.
Noise Reduction
To minimize power supply noise, 0.1µF capacitors should be
placed as close as possible to the converter’s power supply
pins, AVDD and DVDD. Also, should the layout be designed
using separate digital and analog ground plan es, these
capacitors should be terminated to the digital ground for
DVDD and to the analog ground for AVDD. Additional filtering
of the power supplies on the board is recommended. See
the Application Note on the HI5760 Evaluation Board for
more information upon availability.
Voltage Reference
The internal voltage reference of the device has a nominal
value of +1.2V with a ±60 ppm/oC drift coefficient over the
full temperature range of the converter. It is recommended
that a 0.1µF capacitor be placed as close as possible to the
REFIO pin, connected to the analog ground. The REFLO
pin (16) selects the reference. The internal reference can
be selected if pin 16 is tied low (ground). If an external
reference is desired, then pin 16 sho uld be tied high (to th e
analog supply voltage) and the external reference driven
into REFIO, pin 17. The full scale output current of the
converter is a function of the voltage reference used and
the value of RSET. IOUT should be withi n the 2mA to 20mA
range, through operation below 2mA is possible, with
performance degradation.
If the internal reference is used, VFSADJ will equal
approximately 1.1 6V (pin 18). If an external reference is used,
VFSADJ will equal the external re ference . The cal culation for
IOUT (Full Scale) is:
IOUT (Full Scale) = (VFSADJ/RSET)x 32
If the full scale output current is set to 20mA by using the
internal voltage reference (1.1 6V) and a 1.86k RSET
resistor, then the input coding to output current wil l resembl e
the following:
Outputs
IOUTA and IOUTB are complementary current outputs. The
sum of the two currents is always equal to the full scale
output current minus one LSB. If single ended use is
desired, a load resistor can be used to convert the output
current to a voltage. It is recommended that the unused
output be either grounded or equally terminated. The voltage
developed at the output must not violate the output voltage
compliance range of -0.3V to 1.25V. RLOAD should be
chosen so that the desired output voltage is produced in
conjunction with the output full scale current, which is
described above in the ‘Refere nce’ section. If a known line
impedance is to be driven, then the output load resistor
should be chosen to match this impedance. The output
voltage equation is:
VOUT = IOUT X RLOAD
These outputs can be used in a differential-to-single-ended
arrangement to achieve better harmon ic rejection. The
SFDR measurements in this data sheet were performed with
a 1:1 transformer on the output of the DAC (see Figure 1).
With the center tap grounded, the output swing of pins 21
and 22 will be biased at zero volts. It is important to note
here that the negative voltage output compliance range limit
is -300mV, imposing a maximum of 600mVP-P amplitude
with this configuration. The loading as shown in Figure 1 will
result in a 500mV signal at the output of the transformer if
the full scale output current of the DAC is set to 20mA.
VOUT = 2 x IOUT x REQ, where REQ is ~12.5
