OPA727AIDRBT from Texas Instruments, in a SON-8-EP(3x3). 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 | NC | unconnected | No internal connection. |
| 2 | -IN | input | Inverting input of the amplifier; input terminals are diode-clamped to the supply rails and signals more than 0.5V beyond the rails should be current limited to 10mA or less. |
| 3 | +IN | input | Non-inverting input of the amplifier; input common-mode range extends from V- to (V+) - 2.5V and signals more than 0.5V beyond the rails should be current limited to 10mA or less. |
| 4 | V- | power_in | Negative supply (or ground in single-supply operation); the exposed thermal die pad must also be connected to V-. |
| 5 | NC | unconnected | No internal connection. |
| 6 | OUT | output | Amplifier output with rail-to-rail swing, within 150mV of the rails for light loads (>100kΩ) and within 250mV with 1kΩ loads. |
| 7 | V+ | power_in | Positive supply, specified for 4V to 12V total supply (absolute maximum 13.2V) and to be bypassed with 1nF ceramic in parallel with 1µF tantalum capacitors. |
| 8 | NC | unconnected | No internal connection. |
| 9 | EP | power_in | Exposed thermal die pad on underside, to be connected to V- and soldered to the PCB thermal pad. |
