OPA348AQDRQ1

Texas Instruments · Operational Amplifier · SOIC-8

OPA348AQDRQ1 from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NC unconnected No internal connection; the datasheet lists this pin as not connected (NC) in the 8-pin SOIC package.
2 -IN input Inverting input; for normal operation the input voltage must stay within (V-) - 0.2 V to (V+) + 0.2 V, and input current must be limited to 10 mA when the input exceeds the supply rails by more than 0.5 V.
3 +IN input Non-inverting input; for normal operation the input voltage must stay within (V-) - 0.2 V to (V+) + 0.2 V, and input current must be limited to 10 mA when the input exceeds the supply rails by more than 0.5 V.
4 V- power_in Negative (lowest) power supply; the device operates from 2.1 V to 5.5 V between V+ and V-.
5 NC unconnected No internal connection; the datasheet lists this pin as not connected (NC) in the 8-pin SOIC package.
6 OUT output Amplifier output; the output can be shorted to ground continuously (one amplifier per package), and the absolute maximum supply voltage is 7.5 V.
7 V+ power_in Positive (highest) power supply; the device operates from 2.1 V to 5.5 V between V+ and V-, with an absolute maximum of 7.5 V.
8 NC unconnected No internal connection; the datasheet lists this pin as not connected (NC) in the 8-pin SOIC package.
