PGA112AIDGSRG4 Description
The PGA112AIDGSRG4 devices (binary and scope gains) offer two analog inputs, a three-pin SPI interface, and software shutdown in a 10-pin, VSSOP package. This PGA112AIDGSRG4 provides internal calibration channels for system-level calibration.
The channels are tied to GND, 0.9 V(CAL), 0.1 V(CAL), and V(REF), respectively. V(CAL) an external voltage connected to Channel 0, is used as the system calibration reference. PGA112AIDGSRG4
