Intersil ISL2853x / ISL2863x Instrumentation Amplifiers

Intersil ISL2853x / ISL2863x Instrumentation Amps

Intersil 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 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 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.
