OPA188AIDBVT 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, which swings to within 15 mV of the supply rails with no load and to 250 mV from the rails with a 10 kΩ load, and may be shorted continuously to ground, V-, or V+. |
| 2 | V- | power_in | Negative (lowest) power supply; the input common-mode range includes V-, and signal inputs must stay between (V-) - 0.5 V and (V+) + 0.5 V. |
| 3 | +IN | input | Non-inverting input; the common-mode voltage range is V- to (V+) - 1.5 V, and input current must be limited to 10 mA or less if the signal can exceed a supply rail by 0.5 V. |
| 4 | -IN | input | Inverting input; the common-mode voltage range is V- to (V+) - 1.5 V, and input current must be limited to 10 mA or less if the signal can exceed a supply rail by 0.5 V. |
| 5 | V+ | power_in | Positive (highest) power supply; the device operates from 4 V to 36 V single-supply or ±2 V to ±18 V dual-supply, and supply voltages above 40 V can cause permanent damage. |
