Product Introduction

is a high-precision PGA280 with digitally-controllable instrumentation amplifier gain and signal integrity detection capabilities.The device offers low bias voltage bias and gain drift, which means a word, good linearity, virtually no 1/f noise signal and superior common mode and supply rejection to support high resolution accurate measurements.Availability and widespread use of lighting and electrical equipment, the device moves to a universal signal measurement that meets the requirements for a de-high-impedance input range.

Prevents large inrush current multiplexing (MUX) switching from special circuits.In addition, the input switching matrix enables easy refactoring and representation of system-level diagnostics-overload conditions.

Configuration Common Input/Output (GPIO) provides several different control and communication features.
