description
The TLC5510 and TLC5510A are CMOS, 8-bit, 20
MSPS analog-to-digital converters (ADCs) that
utilize a semiflash architecture. The TLC5510 and
TLC5510A operate with a single 5-V supply and
typically consume only 130 mW of power.
Included is an internal sample-and-hold circuit,
parallel outputs with high-impedance mode, and
internal reference resistors.
The semiflash architecture reduces power
consumption and die size compared to flash
converters. By implementing the conversion in a
2-step process, the number of comparators is
significantly reduced. The latency of the data
output valid is 2.5 clocks.
The TLC5510 uses the three internal reference
resistors to create a standard, 2-V, full-scale
conversion range using VDDA. Only external jumpers are required to implement this option and eliminates the
need for external reference resistors. The TLC5510A uses only the center internal resistor section with an
externally applied 4-V reference such that a 4-V input signal can be used. Differential linearity is 0.5 LSB at 25°C
and a maximum of 0.75 LSB over the full operating temperature range. T ypical dynamic specifications include
a differential gain of 1% and differential phase of 0.7 degrees.
The TLC5510 and TLC5510A are characterized for operation from –20°C to 75°C.

The reference voltage levels for the TLC5510 are derived through an internal resistor divider between VDDA and ground and therefore are not
derived from a separate external voltage source (see the electrical characteristics and text). For the 4 V input range of the TLC5510A, the
reference voltage is externally applied across the center divider resistor.

PRINCIPLES OF OPERATION
functional description
The TLC5510 and TLC5510A are semiflash ADCs featuring two lower comparator blocks of four bits each.
As shown in Figure 2, input voltage VI(1) is sampled with the falling edge of CLK1 to the upper comparators block
and the lower comparators block(A), S(1). The upper comparators block finalizes the upper data UD(1) with the
rising edge of CLK2, and simultaneously, the lower reference voltage generates the voltage RV(1)
corresponding to the upper data. The lower comparators block (A) finalizes the lower data LD(1) with the rising
edge of CLK3. UD(1) and LD(1) are combined and output as OUT(1) with the rising edge of CLK4. As shown
in Figure 2, the output data is delayed 2.5 clocks from the analog input voltage sampling point.
Input voltage VI(2) is sampled with the falling edge of CLK2. UD(2) is finalized with the rising edge of CLK3, and
LD(2) is finalized with the rising edge of CLK4 at the lower comparators block(B). OUT(2) data appears with
the rising edge of CLK5.

internal referencing
TLC5510
The three internal resistors shown with VDDA can generate a 2-V reference voltage. These resistors are brought
out on VDDA, REFTS, REFT, REFB, REFBS, and AGND.
To use the internally generated reference voltage, terminal connections should be made as shown in Figure 3.
This connection provides the standard video 2-V reference for the nominal digital output.

APPLICATION INFORMATION
The following notes are design recommendations that should be used with the device.
D
External analog and digital circuitry should be physically separated and shielded as much as possible to
reduce system noise.
D
RF breadboarding or printed-circuit-board (PCB) techniques should be used throughout the evaluation and
production process. Breadboards should be copper clad for bench evaluation.
D
Since AGND and DGND are connected internally , the ground lead in must be kept as noise free as possible.
A good method to use is twisted-pair cables for the supply lines to minimize noise pickup. An analog and
digital ground plane should be used on PCB layouts when additional logic devices are used. The AGND
and DGND terminals of the device should be tied to the analog ground plane.
D
VDDA to AGND and VDDD to DGND should be decoupled with 1-µF and 0.01-µF capacitors, respectively,
and placed as close as possible to the affected device terminals. A ceramic-chip capacitor is recommended
for the 0.01-µF capacitor . Care should be exercised to ensure a solid noise-free ground connection for the
analog and digital ground terminals.
D
VDDA, AGND, and ANALOG IN should be shielded from the higher frequency terminals, CLK and D0D7.
When possible, AGND traces should be placed on both sides of the ANALOG IN traces on the PCB for
shielding.
D
In testing or application of the device, the resistance of the driving source connected to the analog input
should be 10 or less within the analog frequency range of interest.
