Description

The PGA849 is a precision, wide-bandwidth programmable gain instrumentation amplifier (PGA) for differential to single ended conversion optimized to drive high-performance analog-to-digital converters (ADCs) with sampling rates up to 1 MSPS without the need for an additional ADC driver. 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 device features super-beta input transistors from Texas Instruments, which provide ultra-low input offset voltage, offset drift, low input bias current, input voltage noise, and current noise.
