OPA355NA 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 | Output pin, continuous ±60 mA and peak ±100 mA output current capability at 5 V, output swing within 100 mV of supply rails. |
| 2 | V- | power_in | Negative power supply rail; ground in single-supply operation or negative rail in dual-supply with total supply range 2.7 V to 5.5 V. |
| 3 | IN+ | input | Noninverting input pin with input voltage range from (V-) - 0.1 V to (V+) - 1.5 V and input bias current of 3 pA typical. |
| 4 | IN- | input | Inverting input pin with input voltage range from (V-) - 0.1 V to (V+) - 1.5 V and input bias current of 3 pA typical. |
| 5 | ENABLE | input | Digital shutdown control pin; logic low (≤0.8 V) disables amplifier reducing quiescent current to 3.4 µA, logic high (≥2 V) enables normal operation; pin must be driven. |
| 6 | V+ | power_in | Positive power supply rail with operating voltage range from 2.7 V to 5.5 V (single-supply up to 5.5 V or ±1.35 to ±2.75 V dual-supply). |
