OPA705UA

Texas Instruments · Operational Amplifier · SOIC-8

OPA705UA 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 internal connection; the pin is not connected to the amplifier circuit.
2 -In input Inverting input; the common-mode voltage range extends from (V-) - 0.3V to (V+) + 0.3V, and input signals more than 0.3V beyond the supply rails should be current-limited to 10mA or less.
3 +In input Non-inverting input; the common-mode voltage range extends from (V-) - 0.3V to (V+) + 0.3V, and input signals more than 0.3V beyond the supply rails should be current-limited to 10mA or less.
4 V- power_in Negative supply rail; the device is specified for dual supplies of ±2V to ±6V or single supply of 4V to 12V (V+ to V- total 13.2V absolute maximum).
5 NC unconnected No internal connection; the pin is not connected to the amplifier circuit.
6 Out output Amplifier output, which swings to within 40mV of the rail at light loads (>100kΩ) and is short-circuit protected to ground (continuous, one amplifier per package).
7 V+ power_in Positive supply rail; the device is specified for dual supplies of ±2V to ±6V or single supply of 4V to 12V (V+ to V- total 13.2V absolute maximum).
8 NC unconnected No internal connection; the pin is not connected to the amplifier circuit.

CAD (KiCad official)

  • Symbol: OPA705UA
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: opa705ua-etched.step / opa705ua-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); opa705ua.step / opa705ua.glb are the bare package body.
