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.

Highlights

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
