UPGRADE FOR THE OPA686, CLC425, AND

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.

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 exceptional

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.
