More Information

The OPA838 decompensated voltage feedback operational amplifier provides a high 300-MHz gain bandwidth product with 1.8-nV/√Hz input noise voltage, requiring only a trimmed 0.95-mA supply current. These features combine to provide an extremely power-efficient solution for photodiode transimpedance designs and high-voltage gain stages, which require the lowest input voltage noise in signal receiver applications.
