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.
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.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not implied.
ELECTROSTATIC DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
