Introduction
The PGA400-Q1 is a generic sensor interface IC for resistive and capacitive sensors. It features
a configurable Analog Front-End (AFE) with diagnostics, Sigma-Delta ADC, 8051
microcontroller, DACs, SPI, I2C, and a One-Wire Interface (OWI).

1 Power Supply Requirements and Connections
There is only one main +9VDC - +12VDC power connector on the PGA400-Q1EVM that
supplies power to the entire board. The user is required to connect a power supply to the
banana jacks, P1 “VPWR” and P3 “GND” or use the screw terminal P2. An example using the
banana jack connections can be seen in the figure below.
