Description

The OPA846 combines very high gain bandwidth and large signal performance with very low input voltage noise, while dissipating a low 12.6mA supply current. The classical differential input stage, along with two stages of forward gain and a high power output stage, combine to make the OPA846 an exceptionally low distortion amplifier with excellent DC accuracy and output drive. The voltage-feedback architecture allows all standard op amp applications to be implemented with very high performance.

The combination of low input voltage and current noise, along with a 1.75GHz gain bandwidth product, make the OPA846 an ideal amplifier for wideband transimpedance stages. As a voltage gain stage, the OPA846 is optimized for a flat response at a gain of +10 and is stable down to a gain of +7.
