TP2274-SR

3PEAK · Operational Amplifier · SOIC-14

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.
