40V Precision Single Supply Rail-to-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 provide 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, MSOP and SOIC
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 of -40°C to +125°C.
