Description

The OPA687 combines a very high gain bandwidth and large signal performance with an ultra-low input noise voltage (0.95nV/ÖHz) while dissipating only 18mA supply current. Where power savings is paramount, the OPA687 also includes an optional power down pin that, when pulled low, will disable the amplifier and decrease the quiescent current to only 1% of its powered up value.

This optional feature may be left disconnected to insure normal amplifier operation when no power-down is required.

The combination of low input voltage and current noise, along with a 3.8GHz gain bandwidth product, make the OPA687 an ideal amplifier for wideband transimpedancestages. As a voltage gain stage, the OPA687 is optimized for a flat frequency response at a gain of +20 and is guaranteed stable down to gains of +12. New external compensation techniques allows the OPA687 to be used at any inverting gain with excellent frequency response control. Using this compensation can give an extremely high dynamic range ADC driver to support > 40MSPS 12- and 14-bit converters.
