Product Description
The PGA281 is a high-precisioninstrumentation amplifier with a digitally-controllable gain and signal- integrity test capability.
This device usesproprietary autozeroing techniques to offer low offset voltage near-zero offset and gain driftexcellent linearity,
and nearly no 1/f noise. The PGA281 is optimized to provide an excellent common-mode rejection of qreater than 110 dB(G=1)
over a wide frequencyrangeSuperior common- mode and supply reiection supports high-resolution precise measurement.
The36-Vsupply capability and wide,high-impedance input range comply with requirements for universal signal measurement.
