MC34072ADR2G from onsemi, in a SOIC-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 | Output 1 | output | Output of Amplifier 1; indefinite short-circuit protection to ground, capable of sourcing/sinking 20 mA minimum at low load resistance. |
| 2 | Inverting input 1 | input | Inverting input of Amplifier 1; input common mode range VEE to (VCC − 1.8 V) at 25°C, maximum differential input voltage ±44 V. |
| 3 | Non-inverting input 1 | input | Non-inverting input of Amplifier 1; input common mode range VEE to (VCC − 1.8 V) at 25°C, maximum differential input voltage ±44 V. |
| 4 | VEE | power_in | Ground/negative supply rail; common return for both amplifiers, sets lower bound of input/output voltage range. |
| 5 | Non-inverting input 2 | input | Non-inverting input of Amplifier 2; input common mode range VEE to (VCC − 1.8 V) at 25°C, maximum differential input voltage ±44 V. |
| 6 | Inverting input 2 | input | Inverting input of Amplifier 2; input common mode range VEE to (VCC − 1.8 V) at 25°C, maximum differential input voltage ±44 V. |
| 7 | Output 2 | output | Output of Amplifier 2; indefinite short-circuit protection to ground, capable of sourcing/sinking 20 mA minimum at low load resistance. |
| 8 | VCC | power_in | Positive supply rail; rated for single supply 3.0 V to 44 V or split supplies with total supply voltage (VCC − VEE) not exceeding 44 V. |
