The PGA112EVM is an evaluation module that is used to fully evaluate the PGA112 programmable gain amplifier. The PGA112EVM consists of two printed circuit boards (PCBs). One board (the SM-USB-DIG Platform) generates the digital signals required to communicate with the PGA112. The second board is the PGA112EVM Target Board. It provides connections to the I2C™ on the SM-USB-DIG Platform board. It also provides connection points for external connection of the Input Voltage, Reference Voltage, SCL and SDA, Output Voltage and Power Supply.
