5V, Rail-Rail I/O, Zero-Drift, Programmable Gain
Instrumentation Amplifiers
ISL28533, ISL28534, ISL28535, ISL28633, ISL28634, ISL28635
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.

CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product
reliability and result in failures not covered by warranty.
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. For θJC, the “case temp” location is taken at the package top center.
Electrical Specifications V+ = 5V, V- = 0V, VIN+ = VIN- = VREF = 2.5V, TA = +25°C, unless otherwise specified. Boldface limits apply over
