描述 Description

The ISL28635 is a 5V zero-drift rail-to-rail input/output (RRIO) Programmable Gain Instrumentation Amplifiers (PGIA). This instrumentation amplifier features low offset, low noise, low gain error, and high CMRR. It is ideal for high precision applications over the wide industrial temperature range. This in-amp is designed with a unique 2-bit, 3-state logic interface that allows up to 9 selectable gain settings. The ISL2863x differential output amplifier includes a reference pin to set the common-mode output voltage to interface with differential input ADCs.
