DESCRIPTIONThe OPA847 combines very high gain bandwidth and large
signal performance with an ultra-low input noise voltage
(0.85nV/√Hz) while using only 18mA supply current. Where
power saving is critical, the OPA847 also includes an op-
tional power shutdown pin that, when pulled low, disables the
amplifier and decreases the supply current to < 1% of the
powered-up value. This optional feature may be left discon-
nected to ensure normal amplifier operation when no power-
down is required.
The combination of very low input voltage and current noise,
along with a 3.9GHz gain bandwidth product, make the
OPA847 an ideal amplifier for wideband transimpedance
applications. As a voltage gain stage, the OPA847 is opti-
mized for a flat frequency response at a gain of +20V/V and
is stable down to gains as low as +12V/V. New external
compensation techniques allow the OPA847 to be used at
any inverting gain with excellent frequency response control.
Using this technique in a differential Analog-to-Digital Con-
verter (ADC) interface application, shown below, can deliver
one of the highest dynamic-range interfaces available.
