The ISL28533, ISL28534, ISL28535, ISL28633, ISL28634,

and ISL28635 are 5V Zero-Drift Rail-to-Rail Input/Output

Programmable Gain Instrumentation Amplifiers (PGIA). These

instrumentation amplifiers feature low offset, low noise, low

gain error and high CMRR. They are ideal for high precision

applications over the wide industrial temperature range.

These Instrumentation Amplifiers are designed with a unique

2-bit, 3-state logic interface that allows up to 9 selectable gain

settings. The ISL2853x single-ended output includes and

additional uncommitted zero-drift amplifier, useful to buffer

the REF input or used as a precision amplifier. The ISL2863x

differential output amplifier includes a reference pin to set the

common mode output voltage to interface with differential

input ADCs.
