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 differ- ential 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 accu-racy 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 it an ideal amplifier for wideband transimpedance stages. As a voltage gain stage, the device is optimized for a flat response at a gain of +10 and is stable down to a gain
of +7.

A new external compensation technique can be used to give a very flat frequency response below the minimum stable gain for the OPA846, further improving its already excep- tional distortion performance. Using this compensation makes the OPA846 one of the premier 12- to 16-bit Analog-to-Digital (A/D) converter input drivers. The supply current for the OPA846 is precisely trimmed to 12.6mA at +25°C. This,along with carefully defined supply current tempco in the input and output stages, combine to provide exceptional performance over the full specified temperature range.
