Our Programmable Gain Amplifier (PGA) portfolio includes low-cost, general-purpose PGAs for cost-sensitive applications. For applications that require higher levels of accuracy, we offer a family of precision programmable gain amplifiers that delivers higher performance. We also offer families that support a standard Serial Peripheral Interface (SPI) 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
