OPA703UA

Texas Instruments · Operational Amplifier · SOIC-8

OPA703UA 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 No connection; the datasheet gives no function or electrical limit for this pin.
2 -In input Inverting input; signals that swing more than 0.3 V beyond the supply rails should be current-limited to 10 mA or less, and the common-mode range is (V-) - 0.3 V to (V+) + 0.3 V.
3 +In input Non-inverting input with the same common-mode range of (V-) - 0.3 V to (V+) + 0.3 V and the same 10 mA input-current limit for signals beyond the rails.
4 V- power_in Negative supply rail; the part is specified for single supply 4 V to 12 V or dual supplies ±2 V to ±6 V, and the absolute maximum total supply V+ to V- is 13.2 V.
5 NC unconnected No connection; the datasheet gives no function or electrical limit for this pin.
6 Out output Amplifier output that swings to within 40 mV of the rail at RL = 100 kΩ, with output current of ±10 mA and short-circuit current of ±40 mA (continuous short-circuit to ground permitted, one amplifier per package).
7 V+ power_in Positive supply rail; the part is specified for single supply 4 V to 12 V or dual supplies ±2 V to ±6 V, and the absolute maximum total supply V+ to V- is 13.2 V.
8 NC unconnected No connection; the datasheet gives no function or electrical limit for this pin.

CAD (KiCad official)

  • Symbol: OPA703UA
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: opa703ua-etched.step / opa703ua-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); opa703ua.step / opa703ua.glb are the bare package body.
