# OPA337NA

**Texas Instruments** · Operational Amplifier · SOT-23-5

OPA337NA from Texas Instruments, in a SOT-23-5. 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 | V+ | power_in | Positive supply voltage; operating range 2.7V to 5.5V, minimum operating voltage 2.5V. |
| 2 | -In | input | Inverting input with common-mode voltage range (V−) − 0.2V to (V+) − 1.2V and maximum input bias current ±10pA. |
| 3 | Out | output | Output with voltage swing from rail of 40 to 125mV (RL = 25kΩ, AOL ≥ 100dB) and maximum short-circuit current ±9mA. |
| 4 | +In | input | Non-inverting input with common-mode voltage range (V−) − 0.2V to (V+) − 1.2V and maximum input bias current ±10pA. |
| 5 | V- | power_in | Negative supply voltage (ground); operating range 2.7V to 5.5V relative to V+. |

## CAD (KiCad official)

- Symbol: `OPA337NA`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-23-5 (KiCad packages3D, STEP)
- 3D model files: `opa337na-etched.step` / `opa337na-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `opa337na.step` / `opa337na.glb` are the bare package body.
