The PGA112 and PGA113 (binary/scope gains) offer two analog inputs, a three-pin SPI interface, and software shutdown in an MSOP-10 package. The PGA116 and PGA117 (binary/scope gains) offer 10 analog inputs, a four-pin SPI interface with daisy-chain capability, and hardware and software shutdown in a TSSOP-20 package.

All versions provide internal calibraTIon channels for system-level calibraTIon. The channels are TIed to GND, 0.9V_CAL, 0.1V_CAL, and V_REF, respecTIvely. V_CAL, an external voltage connected to Channel 0, is used as the system calibration reference. Binary gains are: 1, 2, 4, 8, 16, 32, 64, and 128; scope gains are: 1, 2, 5, 10, 20, 50, 100, and 200.
