2.1.3 EVM Interface

The LDC5072Q1EVM can be powered with 5V across J1 (VCC) and J2 (GND) placed on the left side of the EVM. Leave jumper J8 uninstalled when using 5V operation. To select 3.3V operation, supply 3.3V to J1 (VCC) and install jumper J8.

The voltage on the AGC pin of the LDC5072-Q1 at start-up determines the automatic gain control settings. The voltage can be easily controlled through the 50kΩ trim potentiometer (R96).
