Jan 13, 2017 5V, Rail-to-Rail I/O, Zero-Drift, Programmable Gain Instrumentation Amplifiers
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. Features 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 an
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. Single-ended output (ISL28533, ISL28534, ISL28535) Ultra high precision front-end amplifier Zero-drift instrumentation amplifier Pin selectable 9 gain settings: G = 1 to 1,000 Rail-to-rail input/output Differential output (ISL28633, ISL28634, ISL28635) RFI filtered inputs improve EMI rejection Single supply . 2.5V to 5.5V Dual supply .
