# OPA373AIDBVR

**Texas Instruments** · Operational Amplifier · SOT-23-6

OPA373AIDBVR from Texas Instruments, in a SOT-23-6. 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; with RL = 100 kΩ it swings to within 18 mV typical (25 mV maximum over temperature) of the supply rails. |
| 2 | V- | power_in | Negative (lowest) power supply pin; operating supply range is 2.7 V to 5.5 V (absolute maximum 7 V). |
| 3 | +IN | input | Non-inverting input; the common-mode range is (V-) - 0.2 V to (V+) + 0.2 V and inputs must be kept within this range for normal operation. |
| 4 | -IN | input | Inverting input; the common-mode range is (V-) - 0.2 V to (V+) + 0.2 V and inputs must be kept within this range for normal operation. |
| 5 | Enable | input | Shutdown control: below (V-) + 0.8 V the amplifier is disabled (quiescent current under 0.5 µA typical), and it is active when above (V-) + 2 V up to V+; input bias current is 0.2 µA. |
| 6 | V+ | power_in | Positive (highest) power supply pin; operating supply range is 2.7 V to 5.5 V (absolute maximum 7 V). |
