PGA849 Evaluation Module
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.
