OPA847IDG4 Datasheet PDF - TI

●The OPA847IDG4 is a wideband voltage-feedback Operational Amplifier with shutdown function. The 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 optional 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 disconnected 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 optimized for a flat frequency response at a gain of +20V/V and is stable down to gains as low as +12V/V.
