LM324PT from STMicroelectronics, in a TSSOP-14. 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 | OUT1 | output | Output of amplifier 1; output voltage swings from near ground to VCC+ minus about 1.5 V and can source/sink current per the datasheet's Isource/Isink limits. |
| 2 | IN1- | input | Inverting input of amplifier 1; input bias current typically 20 nA and input common-mode voltage range includes ground. |
| 3 | IN1+ | input | Non-inverting input of amplifier 1; input common-mode voltage range extends from ground to VCC+ minus 1.5 V. |
| 4 | VCC+ | power_in | Positive supply pin for all four amplifiers; single supply operation from +3 V to +30 V (or dual supplies ±1.5 V to ±15 V). |
| 5 | IN2+ | input | Non-inverting input of amplifier 2; input common-mode voltage range includes ground. |
| 6 | IN2- | input | Inverting input of amplifier 2; low input bias current typically 20 nA. |
| 7 | OUT2 | output | Output of amplifier 2; capable of sourcing/sinking output current as specified in the electrical characteristics table. |
| 8 | OUT3 | output | Output of amplifier 3; capable of sourcing/sinking output current as specified in the electrical characteristics table. |
| 9 | IN3- | input | Inverting input of amplifier 3; low input bias current typically 20 nA. |
| 10 | IN3+ | input | Non-inverting input of amplifier 3; input common-mode voltage range includes ground. |
| 11 | VCC- | power_in | Negative supply/ground reference pin for all four amplifiers, common to ground in single-supply operation; supports dual supplies down to -15 V. |
| 12 | IN4+ | input | Non-inverting input of amplifier 4; input common-mode voltage range includes ground. |
| 13 | IN4- | input | Inverting input of amplifier 4; low input bias current typically 20 nA. |
| 14 | OUT4 | output | Output of amplifier 4; output voltage swings from near ground to VCC+ minus about 1.5 V and can source/sink current per the datasheet's Isource/Isink limits. |
