OPA838IDBVT 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 | VOUT | output | Amplifier output pin; the output swings rail-to-rail, and linear operation needs about 100 mV of margin from the supply rails. |
| 2 | VS- | power_in | Negative power supply input; in single-supply use this pin is tied to ground, and the total supply range is 2.7 V to 5.4 V. |
| 3 | VIN+ | power_in | Non-inverting input; the linear input range extends down to VS- and up to about 1.3 V below VS+. |
| 4 | VIN- | power_in | Inverting input; in linear operation it sits at the same voltage as VIN+ with near-zero differential voltage. |
| 5 | PD | input | Power-down pin referenced to VS-: logic low (at or below VS- + 0.55 V) disables the amplifier and logic high (at or above VS- + 1.5 V) enables it, and it must be actively driven rather than left floating. |
| 6 | VS+ | power_in | Positive power supply input; the rated operating supply voltage is 2.7 V to 5.4 V. |
