MCP6S21-I/MS

MCP6S21-I/MS is a one-channel, low-gain PGA. This can be configured for gains from +1 V/V to +32 V/V and the input multiplexer can select one of up to eight channels through an SPI port. The serial interface can also put the PGA into shutdown to conserve power. This PGA is optimized for high speed, low offset voltage, and single-supply operation with rail-to-rail input and output capability. This specification supports single-supply applications needing flexible performance or multiple inputs. Typical application includes A/D converter driver, multiplexed analogue applications, data acquisition, industrial instrumentation, test equipment, and medical instrumentation.
