Like the PGA308, the PGA309 is an Auto-Zero sensor amplifier with programmable gain and offset. Additionally, the PGA309 has an on-board temperature sensor that can adjust for drift, and linearity. The programmable gain and offset both include coarse and fine adjustments. The UART-compatible one wire serial interface simplifies system design and programming. Because of the PGA309’s feature set, it is also ideal for use in bridge sensors, remote 4-20ma transmitters, strain, load, and weigh scales, and automotive sensors, as well as many other applications.
