ISL55190, ISL55290

Single and Dual Ultra-Low Noise, Ultra-Low

Distortion, Low Power Op Amp

The ISL55190 and ISL55290 are single and dual high speed

operational amplifiers featuring low noise, low distortion, and

rail-to-rail output drive capability. They are designed to

operate with single and dual supplies from +5VDC

(±2.5VDC) down to +3VDC (±1.5VDC). These amplifiers

draw 16mA of quiescent supply current per amplifier. For

power conservation, this family offers a low-power shutdown

mode that reduces supply current to 21µA and places the

amplifiers' output into a high impedance state. The ISL55190

ENABLE logic places the device in the shutdown mode with

EN = 0 and the ISL55290 is placed in the shutdown mode

with EN = 1.

These amplifiers have excellent input and output overload

recovery times and outputs that swing rail-to-rail. Their input

common mode voltage range includes ground. The

ISL55190 and ISL55290 are stable at gains as low as 5 with

an input referred noise voltage of 1.2nV/√Hz and harmonic

distortion products -95dBc (2nd) and -92dBc (3rd) below a

4MHz 2VP-P signal.

The ISL55190 is available in space-saving 8 Ld DFN and 8 Ld

SOIC packages. The ISL55290 is available in a 10 Ld MSOP

package.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free

material sets; molding compounds/die attach materials and 100% matte

tin plate termination finish, which are RoHS compliant and compatible

with both SnPb and Pb-free soldering operations. Intersil Pb-free

products are MSL classified at Pb-free peak reflow temperatures that

meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.

Applications Information

Product Descr iption

The ISL55190 and ISL55290 are single and dual high

speed, voltage feedback amplifiers designed for fast pulse

applications, as well as communication and imaging systems

that require very low voltage and current noise. Both devices

are stable at a minimum gain of 5 and feature low distortion

while drawing moderately low supply current. The ISL55190

and ISL55290 use a classical voltage-feedback topology,

which allows them to be used in a variety of high speed

applications where current-feedback amplifiers are not

appropriate due to restrictions placed upon the feedback

element used with the amplifier.

Enable/Power-Down

Both devices can be operated from a single supply with a

voltage range of +3V to +5V, or from split ±1.5V to ±2.5V.

The logic level input to the ENABLE pins are TTL compatible

and are referenced to the -V terminal in both single and split

supply applications. The following discussion assumes

single supply operation.

The ISL55190 uses a logic “0” (<0.8V) to disable the

amplifier and the ISL55290 uses a logic “1” (>2V) to disable

its amplifiers. In this condition, the output(s) will be in a high

impedance state and the amplifier(s) current will be reduced

to 21µA. The ISL55190 has an internal pull-up on the EN pin

and is enabled by either floating or tying the EN pin to a

voltage >2V. The ISL55290 has internal pull-downs on the

EN pins and are enabled by either floating or tying the EN

pins to a voltage <0.8V. The enable pins should be tied

directly to their respective supply pins when not being used

(EN tied to -V for the ISL55290 and EN tied to +V for the

ISL55190).

Current Limiting

The ISL55190 and ISL55290 have no internal current-

limiting circuitry. If the output is shorted, it is possible to

exceed the Absolute Maximum Rating for output current or

power dissipation, potentially resulting in the destruction of

the device.

Power Dissipation

It is possible to exceed the +125°C maximum junction

temperatures under certain load and power-supply

conditions. It is therefore important to calculate the

maximum junction temperature (TJMAX) for all applications

to determine if power supply voltages, load conditions, or

package type need to be modified to remain in the safe

operating area. These parameters are related using

Equation 1:

where:

•P

DMAXTOTAL is the sum of the maximum power

dissipation of each amplifier in the package (PDMAX)

•PD

MAX for each amplifier can be calculated using

Equation 2:

where:

•T

MAX = Maximum ambient temperature

•θJA = Thermal resistance of the package

•PD

MAX = Maximum power dissipation of 1 amplifier

•V

S = Supply voltage

•I

MAX = Maximum supply current of 1 amplifier

•V

OUTMAX = Maximum output voltage swing of the

application

•R

L = Load resistance

Power Supply Bypassing and Printed Circuit

Board Layout

As with any high frequency device, good printed circuit

board layout is necessary for optimum performance. Low

impedance ground plane construction is essential. Surface

mount components are recommended, but if leaded

components are used, lead lengths should be as short as

possible. The power supply pins must be well bypassed to

reduce the risk of oscillation. The combination of a 4.7µF

tantalum capacitor in parallel with a 0.01µF capacitor has

been shown to work well when placed at each supply pin.

For good AC performance, parasitic capacitance should be

kept to a minimum, especially at the inverting input. When

ground plane construction is used, it should be removed

from the area near the inverting input to minimize any stray

capacitance at that node. Carbon or Metal-Film resistors are

acceptable with the Metal-Film resistors giving slightly less

peaking and bandwidth because of additio nal series

inductance. Use of sockets (particularly for the SOIC

package) should be avoided if possible. Sockets add

parasitic inductance and capacitance which, will result in

additional peaking and overshoot.

For inverting gains, this parasitic capacitance has little ef fect

because the inverting input is a virtual ground, but for non-

inverting gains, this capacitance (in conjunction with the

feedback and gain resistors) creates a pole in the feedback

path of the amplifier. This pole, if low enough in frequency,

has the same destabilizing effect as a zero in the forward

open-loop response. The use of large-value feedback and

gain resistors exacerbates the problem by further lowering

the pole frequency (increasing t he possibility of oscillation).

March 30, 2007

The ISL55190 single has a dedicated feedback pin which is

internally connected to the amplifier output and located next

to the inverting input pin. This additional output connection

enables the PC board trace capacitance at the inverting pin

to be minimized.

Current Sense Application Circuit

The schematic in Figure 47 provides an example of utilizing

the ISL55190 high speed performance with the ground

sensing input capability to implement a single-supply , G =1 0

differential low side current sense amplifier. This circuit can

be used to sense currents of either polarity. Th e reference

voltage applied to VREF (+2.5V) defines the amplifier outp ut

0A current sense reference voltage at one half the supply

voltage level (VS = +5VDC), and RSENSE sets the current

sense gain and full scale values. In this example the current

gain is 10A/V over a maximum current range of slightly less

than ±25A with RSENSE = 0.01Ω. The amplifier VIO error

(-1.1mV max) and input bias offset current (IIO) error (1.3µA)

together contribute less than 15mV (150mA) at the output for

better than 0.3% full scale accuracy.

The amplifier’s high slew rate and fast pulse response make

this circuit suitable for low-side current sensing in PWM and

motor control applications. The excellent input overload

recovery response enables the circuit to maintain

performance in the presence of parasitic inductance that can

cause fast rise and falling edge spikes that can momentarily

overload the input stage of the amplifier.
