# TP2402-VR

**3PEAK** · Precision Op Amps · MSOP-8

TP2402-VR from 3PEAK, in a MSOP-8. 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; the voltage range extends to within an unspecified number of mV of each supply rail (the value is missing from the datasheet text). |
| 2 | -IN A | input | Inverting input of amplifier A. |
| 3 | +IN A | input | Non-inverting input of amplifier A; inputs are ESD-protected to each supply and exceeding the rails by more than 500 mV requires input current limited to less than 10 mA. |
| 4 | -VS | power_in | Negative power supply (V-), normally tied to ground; it may be tied to another voltage as long as the V+ to V- span is 2.2 V to 5.5 V. |
| 5 | +IN B | input | Non-inverting input of amplifier B; inputs are ESD-protected to each supply and exceeding the rails by more than 500 mV requires input current limited to less than 10 mA. |
| 6 | -IN B | input | Inverting input of amplifier B. |
| 7 | OUT B | output | Amplifier B output; the voltage range extends to within an unspecified number of mV of each supply rail (the value is missing from the datasheet text). |
| 8 | +VS | power_in | Positive power supply (V+), typically 2.2 V to 5.5 V single supply; bypass with 0.1 µF as close to the part as possible. |
