Description
The Microchip Technology Inc. MCP6G01/2/3/4 are
analog Selectable Gain Amplifiers (SGA). They can be
configured for gains of +1 V/V, +10 V/V, and +50 V/V
through the Gain Select input pin(s). The Chip Select
pin on the MCP6G03 can put it into shutdown to
conserve power. These SGAs are optimized for single
supply applications requiring reasonable quiescent
current and speed.
The single amplifier MCP6G01 and MCP6G03, and the
dual amplifier MCP6G02, are available in 8-pin SOIC
and MSOP packages. The quad amplifier MCP6G04 is
available in 14-pin SOIC and TSSOP packages. All
parts are fully specified from -40°C to +125°C.
