Renesas' ISL28533, ISL28534, ISL28535, ISL28633, ISL28634, and ISL28635 are 5 V, 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 nine selectable gain settings. The ISL2853x, single-ended output includes an additional uncommitted, zero-drift amplifier, useful to buffer the REF input or use 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.
