# XL158

**XINLUDA** · Operational Amplifier · SOP-8

XL158 from XINLUDA, in a SOP-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 | OUT1 | output | Output of op-amp A. Can source up to ~40 mA and swings from 0 V to (VCC+ - 1.5 V). |
| 2 | IN1- | input | Inverting input of op-amp A. Input bias current typ. 20 nA; input offset voltage typ. 2 mV. |
| 3 | IN1+ | input | Non-inverting input of op-amp A. Common-mode range includes ground (0 V to VCC+ - 1.5 V). |
| 4 | GND | power_in | Negative supply / ground (VCC-). In single-supply operation connect to 0 V; in split-supply operation this is the negative rail. |
| 5 | IN2+ | input | Non-inverting input of op-amp B. Common-mode range includes ground (0 V to VCC+ - 1.5 V). |
| 6 | IN2- | input | Inverting input of op-amp B. Input bias current typ. 20 nA; input offset voltage typ. 2 mV. |
| 7 | OUT2 | output | Output of op-amp B. Can source up to ~40 mA and swings from 0 V to (VCC+ - 1.5 V). |
| 8 | VCC | power_in | Positive supply (VCC+). Operating range 3 V to 30 V single-supply, or ±1.5 V to ±16 V split-supply. Absolute max ±16 V split / 32 V single. |

## CAD (KiCad official)

- Symbol: `XL158`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOP-8 (KiCad packages3D, STEP)
- 3D model files: `xl158-etched.step` / `xl158-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `xl158.step` / `xl158.glb` are the bare package body.
