OPA320AQDBVTQ1

Texas Instruments · Operational Amplifier · SOT-23-5

OPA320AQDBVTQ1 from Texas Instruments, in a SOT-23-5. 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 OUT output Amplifier output; the output stage has an open-loop output impedance of about 90 Ω and the datasheet specifies a continuous short-circuit current to ground for one amplifier per package.
2 V- power_in Negative supply or ground for single-supply operation; the total supply range is 1.8 V to 5.5 V single-supply or ±0.9 V to ±2.75 V dual-supply.
3 +IN input Noninverting input; input signals that swing more than 0.5 V beyond the supply rails should be current-limited to 10 mA or less.
4 -IN input Inverting input; input signals that swing more than 0.5 V beyond the supply rails should be current-limited to 10 mA or less.
5 V+ power_in Positive supply; the absolute maximum supply voltage between V+ and V- is 6 V.
