OPA847IDRG4

Wideband, Ultra-Low Noise, Voltage Feedback Operational Amplifier with Shutdown 8-SOIC -40℃ to 85℃

DESCRIPON

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 savings 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.
