Programmable Gain Amplifiers

Microchip’s Programmable Gain Amplifier (PGA) portfolio includes low-cost, general-purpose programmable gain amplifiers for cost-sensitive applications. For those applications that require higher levels of accuracy, a family of precision programmable gain amplifiers provide increased performance. With families that support a standard SPI interface and on-chip multiplexer as well as devices that offer pin programmable gain options, these highly integrated devices are ideal for space-constrained applications.


  • Integrated mux reduces design complexity by providing up to eight input channels
  • Factory trimming provides a low maximum input voltage of only 275 µV to maintain high levels of gain accuracy
  • Selectable gains up to 32x with eight gain options provide additional system flexibility
  • MCP6G0x series offers pin selectable gains of 1x, 10x and 50x without the use of external resistors, reducing component count and solution size
