# OPA244NA

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

OPA244NA 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 | Amplifier output; the datasheet specifies swing to within about 0.75 V of V+ and 0.1 V of ground for RL = 20kΩ to ground, with short-circuit current of -25/+12 mA. |
| 2 | V- | power_in | Negative supply rail; ground for single-supply operation, with the supply range given as 2.2 V to 36 V single supply or ±1.1 V to ±18 V dual supply. |
| 3 | +In | input | Non-inverting input; the common-mode voltage range is 0 V to (V+) - 0.9 V and includes ground, and inputs are diode-clamped to the rails with input current limited to 10 mA if the input can exceed a rail by more than 0.3 V. |
| 4 | -In | input | Inverting input; the common-mode voltage range is 0 V to (V+) - 0.9 V and inputs are diode-clamped to the rails with input current limited to 10 mA if the input can exceed a rail by more than 0.3 V. |
| 5 | V+ | power_in | Positive supply rail; specified from +2.6 V to +36 V single supply (minimum operating voltage +2.2 V), with absolute maximum supply voltage of 36 V. |

## CAD (KiCad official)

- Symbol: `OPA244NA`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-23-5 (KiCad packages3D, STEP)
- 3D model files: `opa244na-etched.step` / `opa244na-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `opa244na.step` / `opa244na.glb` are the bare package body.
