PGA849 Description
The PGA849 is a wide-bandwidth, low-noise programmable gain instrumentation amplifier for differential-to-single-ended conversion. The PGA849 is equipped with eight binary gain settings, from an attenuating gain of 0.125V/V to a maximum of 16V/V, using three digital gain selection pins. The PGA849 architecture is optimized to drive inputs of high-resolution, precision analog-to-digital converters (ADCs) with...
