PGA204AU/1KG4

Instrumentation, Op Amps, Buffer Amps Overview

The PGA204AU/1KG4 is a programmable gain instrumentation amplifier manufactured by Texas Instruments, belonging to the PGA204 series. It features a single channel with a 3dB bandwidth of 1 MHz and a slew rate of 300 mV/us. The device offers a common-mode rejection ratio (CMRR) of 106 dB, an input bias current of 2 nA, and an input offset voltage of 50 uV. Operating on a power supply range from 9 V to 36 V, it draws 5.2 mA of working current. The unit supports gains of 1, 10, 100, and 1000 V/V, with a maximum input resistance of 10 GOhms. It operates within a temperature range of -40 C to +85 C and is housed in a SOIC-16 surface-mount package.
