OPA244UA

Texas Instruments · Operational Amplifier · SOIC-8

OPA244UA from Texas Instruments, in a SOIC-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 Marked NC on the pinout drawing; the datasheet states no function or connection for this pin.
2 -In input Inverting input; the common-mode input range is 0 V to (V+) - 0.9 V, and inputs are diode-clamped to the supply rails and should be limited to 10 mA if they can exceed the rails by more than 0.3 V.
3 +In input Non-inverting input; the common-mode input range is 0 V to (V+) - 0.9 V, and inputs are diode-clamped to the supply rails and should be limited to 10 mA if they can exceed the rails by more than 0.3 V.
4 V- power_in Negative supply; the part runs from dual supplies of +/-1.1 V to +/-18 V or from a single supply of +2.2 V to +36 V, with the input range referenced to V-.
5 NC unconnected Marked NC on the pinout drawing; the datasheet states no function or connection for this pin.
6 Output output Amplifier output; short-circuit current is -25/+12 mA and the output may be shorted continuously to ground (one amplifier per package).
7 V+ power_in Positive supply; the specified supply range is +2.6 V to +36 V, the minimum operating voltage is +2.2 V, and the absolute maximum supply (V+ to V-) is 36 V.
8 NC unconnected Marked NC on the pinout drawing; the datasheet states no function or connection for this pin.

CAD (KiCad official)

  • Symbol: OPA244UA
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: opa244ua-etched.step / opa244ua-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); opa244ua.step / opa244ua.glb are the bare package body.
