UA741CDTR

XBLW · Operational Amplifier · SOP-8

UA741CDTR from XBLW, in a SOP-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 OFFSET NULL input Offset null pin used to eliminate the offset voltage and balance the input voltages.
2 INVERTING INPUT input Inverting signal input; the closed-loop gain is set by the feedback and input resistors connected to this pin.
3 NONINVERTING INPUT input Noninverting signal input, where the signal is applied in the noninverting amplifier application circuit.
4 V- power_in Negative supply voltage; the absolute maximum supply voltage is ±22 V and the datasheet characterizes the device at ±15 V.
5 OFFSET NULL input Offset null pin used to eliminate the offset voltage and balance the input voltages.
6 OUTPUT output Amplified signal output; the output short circuit duration is specified as continuous.
7 V+ power_in Positive supply voltage; the absolute maximum supply voltage is ±22 V and the datasheet characterizes the device at ±15 V.
8 NC unconnected No connect; should be left floating.
