LM258APT

STMicroelectronics · Operational Amplifier · TSSOP-8

LM258APT from STMicroelectronics, in a TSSOP-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 Out1 output Output of amplifier 1, swinging from 0 V to (VCC+ - 1.5 V) with output short-circuit current of approximately 40 mA.
2 In1- input Inverting input of amplifier 1, with common-mode range from VCC- to (VCC+ - 1.5 V) at 25 °C and input voltage of -0.3 to 32 V.
3 In1+ input Non-inverting input of amplifier 1, with common-mode range from VCC- to (VCC+ - 1.5 V) at 25 °C and input voltage of -0.3 to 32 V.
4 Vcc- power_in Negative supply voltage, ground in single-supply operation.
5 In2+ input Non-inverting input of amplifier 2, with common-mode range from VCC- to (VCC+ - 1.5 V) at 25 °C and input voltage of -0.3 to 32 V.
6 In2- input Inverting input of amplifier 2, with common-mode range from VCC- to (VCC+ - 1.5 V) at 25 °C and input voltage of -0.3 to 32 V.
7 Out2 output Output of amplifier 2, swinging from 0 V to (VCC+ - 1.5 V) with output short-circuit current of approximately 40 mA.
8 Vcc+ power_in Positive supply voltage, operating range 3 V to 30 V.
