PGA280 Description
The PGA280 is a high-precision instrumentation amplifier with digitally-controllable gain and signal integrity test capability. This device offers low offset voltage, near-zero offset and gain drift, excellent linearity, and nearly no 1/f noise with superior mon-mode and supply rejection to support highresolution precision measurement. The 36-V supply capability and wide, high-impedance input range ply with...
