TP2274-SR from 3PEAK, in a SOIC-14. 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 A | output | Amplifier A output, whose voltage range extends to within milli-volts of each supply rail. |
| 2 | -In A | input | Amplifier A inverting input, voltage range from V- to (V+ - 2.0V). |
| 3 | +In A | input | Amplifier A non-inverting input, with the same voltage range as -IN (V- to V+ - 2.0V). |
| 4 | +Vs | power_in | Positive power supply, 2.7V to 36V between V+ and V-, with a 0.1uF bypass capacitor placed close to the part. |
| 5 | +In B | input | Amplifier B non-inverting input, voltage range from V- to (V+ - 2.0V). |
| 6 | -In B | input | Amplifier B inverting input, voltage range from V- to (V+ - 2.0V). |
| 7 | Out B | output | Amplifier B output, whose voltage range extends to within milli-volts of each supply rail. |
| 8 | Out C | output | Amplifier C output, whose voltage range extends to within milli-volts of each supply rail. |
| 9 | -In C | input | Amplifier C inverting input, voltage range from V- to (V+ - 2.0V). |
| 10 | +In C | input | Amplifier C non-inverting input, voltage range from V- to (V+ - 2.0V). |
| 11 | -Vs | power_in | Negative power supply, normally tied to ground; V+ to V- must be 2.7V to 36V, and bypass with 0.1uF if not grounded. |
| 12 | +In D | input | Amplifier D non-inverting input, voltage range from V- to (V+ - 2.0V). |
| 13 | -In D | input | Amplifier D inverting input, voltage range from V- to (V+ - 2.0V). |
| 14 | Out D | output | Amplifier D output, whose voltage range extends to within milli-volts of each supply rail. |
