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.
