The OPA455EVM can be configured from ±6 V to ±75 V for dual-supply operation, or from 12 V to 150 V for single-supply operation. Shorting pins 2 and 3 of J5 sets the EVM to single supply, and shorting pins 1 and 2 of J5 sets up the EVM for dual supplies. The OPA455 is capable of sourcing or sinking up to 30 mA of current. Power is provided to the EVM through J2 (V+) and J1 (V–). Take care to select supplies capable of providing the required power for the application. Use a supply capable of supplying at least twice the anticipated current at the intended operating voltage.
