## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1OUT | output | Output of op-amp 1. Can source up to ~10mA and sink up to ~5mA at VCC=5V. |
| 2 | 1IN- | input | Inverting (negative) input of op-amp 1. Input bias current 2nA typical, 20nA max. |
| 3 | 1IN+ | input | Non-inverting (positive) input of op-amp 1. Common-mode range includes ground; up to VCC-1.5V. |
| 4 | VCC+ | power_in | Positive (highest) supply. Operating range 3V to 32V single-supply, or ±16V dual-supply. Absolute maximum 32V. |
| 5 | 2IN+ | input | Non-inverting (positive) input of op-amp 2. Common-mode range includes ground. |
| 6 | 2IN- | input | Inverting (negative) input of op-amp 2. Input bias current 2nA typical. |
| 7 | 2OUT | output | Output of op-amp 2. Can source up to ~10mA and sink up to ~5mA at VCC=5V. |
| 8 | 3OUT | output | Output of op-amp 3. Can source up to ~10mA and sink up to ~5mA at VCC=5V. |
| 9 | 3IN- | input | Inverting (negative) input of op-amp 3. Input bias current 2nA typical. |
| 10 | 3IN+ | input | Non-inverting (positive) input of op-amp 3. Common-mode range includes ground. |
| 11 | VCC- | power_in | Negative (lowest) supply or ground for single-supply operation. Tie to GND for single-supply; tie to negative rail for split-supply. |
| 12 | 4IN+ | input | Non-inverting (positive) input of op-amp 4. Common-mode range includes ground. |
| 13 | 4IN- | input | Inverting (negative) input of op-amp 4. Input bias current 2nA typical. |
| 14 | 4OUT | output | Output of op-amp 4. Can source up to ~10mA and sink up to ~5mA at VCC=5V. |

## CAD (KiCad official)

- Symbol: `LP2902DR`
- Footprint: `Package_SO:SOIC-14_3.9x8.7mm_P1.27mm`
- 3D model: SOIC-14 (KiCad packages3D, STEP)
- 3D model files: `lp2902dr-etched.step` / `lp2902dr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lp2902dr.step` / `lp2902dr.glb` are the bare package body.
