# OPA336U

**Texas Instruments** · Precision Op Amps · SOIC-8

OPA336U from Texas Instruments, in a SOIC-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 | NC | unconnected | No-connection pin, not internally connected to the amplifier. |
| 2 | -In | input | Inverting input; the common-mode range extends from V- to (V+) - 1V at a 5V supply, and input signals more than 0.3V beyond the rails should be current-limited to 10mA or less. |
| 3 | +In | input | Non-inverting input; the common-mode range extends from V- (-0.2V typ. at 5V supply) to (V+) - 1V, and input signals more than 0.3V beyond the rails should be current-limited to 10mA or less. |
| 4 | V- | power_in | Negative power supply rail; the device is specified for a total supply of 2.3V to 5.5V and the common-mode range extends to this rail. |
| 5 | NC | unconnected | No-connection pin, not internally connected to the amplifier. |
| 6 | Output | output | Rail-to-rail output that swings to within 3mV of the supplies with a 100kΩ load, with continuous short-circuit protection to ground for one amplifier per package. |
| 7 | V+ | power_in | Positive power supply; specified from 2.3V to 5.5V with an absolute maximum supply of 7.5V. |
| 8 | NC | unconnected | No-connection pin, not internally connected to the amplifier. |

## CAD (KiCad official)

- Symbol: `OPA336U`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOIC-8 (KiCad packages3D, STEP)
- 3D model files: `opa336u-etched.step` / `opa336u-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `opa336u.step` / `opa336u.glb` are the bare package body.
