MCP6S91/2/3
Single-Ended, Rail-to-Rail I/O, Low-Gain PGA
Features Description Multiplexed Inputs: 1 or 2 channels 8 Gain Selections:
-+1, +2, +4, +5, +8, +10, +16 or +32 V/V Serial Peripheral Interface (SPIв„ў) Rail-to-Rail Input and Output Low Gain Error: В±1% (max.) Offset Mismatch Between Channels: 0 ВµV High Bandwidth: 1 to 18 MHz (typ.) Low Noise: 10 nV/в€љHz @ 10 kHz (typ.) Low Supply Current: 1.0 mA (typ.) Single Supply: 2.5V to 5.5V Extended Temperature Range: -40В°C to +125В°C The Microchip Technology Inc. MCP6S91/2/3 are
analog Programmable Gain Amplifiers (PGAs). They
can be configured for gains from +1 V/V to +32 V/V and
the input multiplexer can select one of up to two channels through a SPI port. The serial interface can also
put the PGA into shutdown to conserve power. These
PGAs are optimized for high-speed, low offset voltage
and single-supply operation with rail-to-rail input and
output capability. These specifications support singlesupply applications needing flexible performance or
multiple inputs. Typical Applications A/D Converter Driver
