LM392MX from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTPUT A (COMPARATOR) | output | Open-collector output of the comparator section (Amplifier A); saturation voltage is typically 250 mV (max 400 mV) at ISINK ≤ 4 mA and is compatible with TTL/CMOS logic levels. |
| 2 | INVERTING INPUT A | input | Inverting input of the comparator (Amplifier A); common-mode voltage range extends from ground to V+ − 1.5V and input should not be driven more than 0.3V negative. |
| 3 | NON-INVERTING INPUT A | input | Non-inverting input of the comparator (Amplifier A); common-mode voltage range extends from ground to V+ − 1.5V with input bias current typically 50 nA. |
| 4 | GND | power_in | Ground/negative supply reference pin common to both the comparator and op amp sections. |
| 5 | NON-INVERTING INPUT B | input | Non-inverting input of the internally compensated operational amplifier (Amplifier B); common-mode voltage range extends from ground to V+ − 1.5V. |
| 6 | INVERTING INPUT B | input | Inverting input of the internally compensated operational amplifier (Amplifier B); input bias current typically 50 nA with input offset current typically 5 nA. |
| 7 | OUTPUT B (OP AMP) | output | Output of the operational amplifier (Amplifier B); output voltage swings from 0V to V+ − 1.5V into a 2 kΩ load, sourcing typically 20 mA and sinking typically 10 mA. |
| 8 | V+ | power_in | Positive supply pin; operates from a single supply of 3V to 32V or a dual/split supply of ±1.5V to ±16V, with supply current typically 0.5 mA at V+ = 5V. |
