1.4 Device Information

The EVM is built with the PGA849RGT device in the 16-pin VQFN package with the thermal pad.

This EVM provides access to the features and measures the performance of the PGA849 device. The PGA849 is equipped with eight binary gain settings, from an attenuating gain of 0.125V/V to a maximum of 16V/V, using three digital gain selection pins. By default, the PGA849EVM programmable gain amplifier is configured to a gain of 0.125V/V. The evaluation board provides shunt jumpers J10, J11, and J12 to set the PGA849 gain.
