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.

NOTES:
4. θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
5. θJA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See Tech
Brief TB379.
6. For θJC, the “case temp” location is the center of the exposed metal pad on the package underside.
7. For θJC, the “case temp” location is taken at the package top center.
IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typical values are for information purposes only. Unless otherwise
noted, all tests are at the specified temperature and are pulsed tests, therefore: TJ = TC = TA
Electrical Specifications VS ±15V, VCM = 0, VO = 0V, RL = Open, TA= +25°C, unless otherwise noted. Boldface limits apply over
the operating temperature range, -40°C to +125°C. Temperature data established by characterization.
