DATASHEET ISL28533, ISL28534, ISL28535, ISL28633, ISL28634, ISL28635 FN8364 Rev.2.02 Jun 4, 2020 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 . . . . . . . . . . . . . . . . . . . . . . . . . ±1.25V to ±2.75V • Low input offset . . . . . . . . . . . . . . . . . . . . . . . . .5µV, Maximum Applications • Low input offset drift . . . . . . . . . . . . . . . . 50nV/°C, Maximum • • • • • • • • • Low gain error. . . . . . . . . . . . . . . .
