40V Precision Single Supply Rail-Rail Output Low

Power Operational Amplifiers

ISL28108, ISL28208, ISL28408

The ISL28108, ISL28208 and ISL28408 are single, dual and

quad low power precision amplifiers optimized for single

supply applications. These devices feature a common mode

input voltage range extending to 0.5V below the V- rail, a

rail-to-rail differential input voltage range for use as a

comparator, and rail-to-rail output voltage swing, which make

them ideal for single supply applications where input

operation at ground is important.

Added features include low offset voltage, and low

temperature drift making them the ideal choice for

applications requiring high DC accuracy. The output stage is

capable of driving large capacitive loads from rail to rail for

excellent ADC driving performance. The devices can operate

for single or dual supply from 3V (±1.5V) to 40V (±20V) and are

fully characterized at ±5V and ±15V. The combination of

precision, low power, and small footprint provides the user with

outstanding value and flexibility relative to similar competitive

parts.

Applications for these amplifiers include precision

instrumentation, data acquisition, precision power supply

control, and industrial control.

The ISL28108 single is offered in 8 Ld TDFN, SOIC and MSOP

packages. The ISL28208 dual amplifier is offered in 8 Ld

TDFN, MSOP, and SOIC packages. The ISL28408 is offered in

14 Ld SOIC package. All devices are offered in standard pin

configurations and operate over the extended temperature

range to -40°C to +125°C.
