    Capability

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

All versions provide internal calibration channels for system-level calibration. The channels are tied to GND, 0.9 VCAL, 0.1 VCAL, and VREF, respectively. VCAL, 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.

PGA113EVM-B — Módulo de evaluación PGA113 Rev B

The PGA113EVM is an evaluation module that is used to fully evaluate the PGA113 programmable gain amplifier. The PGA113EVM consists of two printed circuit boards (PCBs). One board (the SM-USB-DIG Platform) generates the digital signals required to communicate with the PGA113. The second board is (...)
