# OPA344PA

**Texas Instruments** · Operational Amplifier · PDIP-8

OPA344PA from Texas Instruments, in a PDIP-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 internal connection. |
| 2 | -In | input | Inverting input, with common-mode range from -0.3V to (V+) + 0.3V and diode-clamped to the supply rails (limit input current to 10mA). |
| 3 | +In | input | Non-inverting input, with common-mode range from -0.3V to (V+) + 0.3V and diode-clamped to the supply rails (limit input current to 10mA). |
| 4 | V- | power_in | Negative supply (ground in single-supply use); total supply V+ to V- is 2.5V to 5.5V operating, 7.5V absolute maximum. |
| 5 | NC | unconnected | No internal connection. |
| 6 | Out | output | Amplifier output, rail-to-rail, with short-circuit current of ±15mA. |
| 7 | V+ | power_in | Positive supply, 2.5V to 5.5V operating (2.7V to 5.5V specified), 7.5V absolute maximum between V+ and V-. |
| 8 | NC | unconnected | No internal connection. |

## CAD (KiCad official)

- Symbol: `OPA344PA`
- Footprint: `Package_DIP:DIP-8_W7.62mm`
- 3D model: PDIP-8 (KiCad packages3D, STEP)
- 3D model files: `opa344pa-etched.step` / `opa344pa-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `opa344pa.step` / `opa344pa.glb` are the bare package body.
