Part Number: OPA1656

The OPA1656 is the industry’s lowest voltage noise high voltage CMOS on the market. It offers exceptional performance in almost any audio application. The low voltage noise combined with the low current noise make this device great for low and high impedance applications such as a high gain microphone pre-amplifier. The high capacitive load drive and high current drive also make this device a great option as a headphone driver.
