OPA656NB 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 | VOUT | output | Output of the amplifier with voltage swing of ±3.7V to ±3.9V (no load, ±5V supplies) and current sourcing/sinking capability of ±50-70mA. |
| 2 | -VS | power_in | Negative power supply terminal operating at -5V to -6V nominal, requiring high-frequency decoupling capacitors for stable operation. |
| 3 | VIN+ | power_in | Noninverting input terminal with JFET input stage, high impedance (≥10¹²Ω), and low input bias current of ±2pA typical. |
| 4 | VIN- | power_in | Inverting input terminal with JFET input stage, high impedance (≥10¹²Ω), and low input bias current of ±2pA typical. |
| 5 | +VS | power_in | Positive power supply terminal operating at +5V to +6V nominal, requiring high-frequency decoupling capacitors for stable operation. |
