LM324S from IDCHIP, in a SOP-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 | OUT1 | output | Output of amplifier channel 1 (输出端1). |
| 2 | -IN1 | input | Inverting input of amplifier channel 1 (反向输入端1); the datasheet notes the part is non-rail-to-rail on both input and output, so the common-mode input range must be respected. |
| 3 | +IN1 | input | Non-inverting input of amplifier channel 1 (同向输入端1); the input common-mode range is specified as -0.1 V to 4 V at VS=5.5 V. |
| 4 | +VS | power_in | Positive power supply pin; the recommended operating supply is +3 V to +30 V single-supply or ±1.5 V to ±15 V split-supply. |
| 5 | +IN2 | input | Non-inverting input of amplifier channel 2 (同向输入端2); the input common-mode range is specified as -0.1 V to 4 V at VS=5.5 V. |
| 6 | -IN2 | input | Inverting input of amplifier channel 2 (反向输入端2); the datasheet notes the part is non-rail-to-rail on both input and output, so the common-mode input range must be respected. |
| 7 | OUT2 | output | Output of amplifier channel 2 (输出端2). |
| 8 | OUT3 | output | Output of amplifier channel 3 (输出端3). |
| 9 | -IN3 | input | Inverting input of amplifier channel 3 (反向输入端3); the datasheet notes the part is non-rail-to-rail on both input and output, so the common-mode input range must be respected. |
| 10 | +IN3 | input | Non-inverting input of amplifier channel 3 (同向输入端3); the input common-mode range is specified as -0.1 V to 4 V at VS=5.5 V. |
| 11 | -VS | power_in | Negative power supply pin (电源负); it is the negative rail in split-supply operation and the ground/Vss reference in single-supply operation. |
| 12 | +IN4 | input | Non-inverting input of amplifier channel 4 (同向输入端4); the input common-mode range is specified as -0.1 V to 4 V at VS=5.5 V. |
| 13 | -IN4 | input | Inverting input of amplifier channel 4 (反向输入端4); the datasheet notes the part is non-rail-to-rail on both input and output, so the common-mode input range must be respected. |
| 14 | OUT4 | output | Output of amplifier channel 4 (输出端4). |
