# OPA353NA

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

OPA353NA 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 | Out | output | Rail-to-rail amplifier output swinging to within 10mV of the supply rails with a 10kΩ load, with ±40mA output current and ±80mA short-circuit current. |
| 2 | V- | power_in | Negative supply, ground in single-supply operation; the total supply (VS) is 2.7V to 5.5V, with 2.5V minimum operating voltage. |
| 3 | +In | input | Non-inverting input with common-mode range of -0.1V to (V+)+0.1V, diode-clamped to the supply rails so signals beyond 0.3V past the rails must be current-limited to 10mA. |
| 4 | -In | input | Inverting input with common-mode range of -0.1V to (V+)+0.1V, diode-clamped to the supply rails so signals beyond 0.3V past the rails must be current-limited to 10mA. |
| 5 | V+ | power_in | Positive supply, 2.7V to 5.5V operating range with 5.5V absolute maximum supply voltage. |

## CAD (KiCad official)

- Symbol: `OPA353NA`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-23-5 (KiCad packages3D, STEP)
- 3D model files: `opa353na-etched.step` / `opa353na-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `opa353na.step` / `opa353na.glb` are the bare package body.
