# XD7650-8

**XINLUDA** · Operational Amplifier · DIP-8

XD7650-8 from XINLUDA, in a DIP-8. 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 | CEXTA | passive | Connection for external nulling storage capacitor CEXTA (0.1µF for the internal clock), the other end going to CRETN. |
| 2 | -IN | input | Inverting input; the OUTPUT CLAMP pin is tied here on 14-pin parts, and no voltage beyond 0.3V past the supply rails may be applied. |
| 3 | +IN | input | Non-inverting input; no voltage beyond 0.3V past the supply rails may be applied. |
| 4 | V- | power_in | Negative supply; total supply V+ to V- operating range is 4.5V to 16V. |
| 5 | CRETN | passive | Capacitor return pin, common connection for the two external nulling capacitors CEXTA and CEXTB. |
| 6 | OUTPUT | output | Amplifier output, high-impedance (about 18kΩ) stage, with a 10kΩ load recommended for full swing. |
| 7 | V+ | power_in | Positive supply; total supply V+ to V- operating range is 4.5V to 16V. |
| 8 | CEXTB | passive | Connection for external nulling storage capacitor CEXTB (0.1µF for the internal clock), the other end going to CRETN. |
