Renesas Electronics ISL2853x & ISL2863x Instrumentation Amplifiers

Renesas Electronics ISL2853x and ISL2863x 5V Zero-Drift Rail-to-Rail Input/Output Programmable Gain Instrumentation Amplifiers (PGIA) feature low offset, low noise, low gain error, and high CMRR. These Renesas / Intersil devices are ideal for high precision applications over the wide industrial temperature range. ISL2853x and ISL2863x amps 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.
