The precision instrumentation amplifier provides programmable gains from 1 to 1000 with one external resistor and operates from ±2.3 V to ±18 V supplies. It maintains at least 80 dB CMRR to 10 kHz at G = 1 and offers 825 kHz small-signal bandwidth at G = 1 with 2 V/µs slew rate. The device is specified from −40°C to +85°C and remains operational to +125°C in 8-lead SOIC_N and 8-lead MSOP package options.
