MC33274ADTBR2G

onsemi · Operational Amplifier · TSSOP-14

MC33274ADTBR2G from onsemi, in a TSSOP-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 Output 1 output Output of amplifier 1; the datasheet notes that the output short-circuit duration is indefinite, and power dissipation must be considered to keep junction temperature within limits.
2 Inputs 1 (-) input Inverting input of amplifier 1; either or both input voltages should not exceed VCC or VEE.
3 Inputs 1 (+) input Non-inverting input of amplifier 1; either or both input voltages should not exceed VCC or VEE.
4 VCC power_in Positive supply; VCC to VEE is rated at a maximum of +36 V, with single supply operation from +3.0 V to +36 V or split supply from ±1.5 V to ±18 V.
5 Inputs 2 (+) input Non-inverting input of amplifier 2; either or both input voltages should not exceed VCC or VEE.
6 Inputs 2 (-) input Inverting input of amplifier 2; either or both input voltages should not exceed VCC or VEE.
7 Output 2 output Output of amplifier 2; the datasheet notes that the output short-circuit duration is indefinite, and power dissipation must be considered to keep junction temperature within limits.
8 Output 3 output Output of amplifier 3; the datasheet notes that the output short-circuit duration is indefinite, and power dissipation must be considered to keep junction temperature within limits.
9 Inputs 3 (-) input Inverting input of amplifier 3; either or both input voltages should not exceed VCC or VEE.
10 Inputs 3 (+) input Non-inverting input of amplifier 3; either or both input voltages should not exceed VCC or VEE.
11 VEE power_in Negative supply; VEE is the lower rail of the VCC to VEE supply, with 0 V used for single supply operation in the 5.0 V test condition.
12 Inputs 4 (+) input Non-inverting input of amplifier 4; either or both input voltages should not exceed VCC or VEE.
13 Inputs 4 (-) input Inverting input of amplifier 4; either or both input voltages should not exceed VCC or VEE.
14 Output 4 output Output of amplifier 4; the datasheet notes that the output short-circuit duration is indefinite, and power dissipation must be considered to keep junction temperature within limits.
