# LM324BDTR

**XBLW** · Operational Amplifier · SOP-14

LM324BDTR from XBLW, 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 1. |
| 2 | IN1- | input | Reverse (inverting) input of amplifier 1. |
| 3 | IN1+ | input | Forward (non-inverting) input of amplifier 1; the pin table prints it as 'Forward Input 2, IN+ (2)', but the pin diagram places it in amplifier 1. |
| 4 | VCC | power_in | Power supply pin; datasheet gives single supply Vcc=3~32V or dual supply ±1.5V~16V. |
| 5 | IN2+ | input | Forward (non-inverting) input of amplifier 2. |
| 6 | IN2- | input | Reverse (inverting) input of amplifier 2; the pin table prints the symbol as 'IN - (1)', but the pin diagram places it in amplifier 2. |
| 7 | OUT2 | output | Output of amplifier 2. |
| 8 | OUT3 | output | Output of amplifier 3. |
| 9 | IN3- | input | Reverse (inverting) input of amplifier 3. |
| 10 | IN3+ | input | Positive (non-inverting) input of amplifier 3. |
| 11 | GND | power_in | Ground pin; the pin diagram labels it VEE, GND. |
| 12 | IN4+ | input | Positive (non-inverting) input of amplifier 4. |
| 13 | IN4- | input | Reverse (inverting) input of amplifier 4. |
| 14 | OUT4 | output | Output of amplifier 4. |

## CAD (KiCad official)

- Symbol: `LM324BDTR`
- Footprint: `Package_SO:SOIC-14_3.9x8.7mm_P1.27mm`
- 3D model: SOP-14 (KiCad packages3D, STEP)
- 3D model files: `lm324bdtr-etched.step` / `lm324bdtr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lm324bdtr.step` / `lm324bdtr.glb` are the bare package body.
