OPA2705UA

Texas Instruments · Pre-ordered Chips · SOIC-8

OPA2705UA 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 Out A output Output of amplifier A, which the datasheet states swings to within 40mV of the supply rail for light loads.
2 -In A input Inverting input of amplifier A; the input common-mode range extends 300mV beyond the supply rails.
3 +In A input Non-inverting input of amplifier A; the input swing extends 300mV beyond the supply rails.
4 V- power_in Negative supply rail; the part is specified for a single supply of 4V to 12V or dual supplies of ±2V to ±6V.
5 +In B input Non-inverting input of amplifier B; the input swing extends 300mV beyond the supply rails.
6 -In B input Inverting input of amplifier B; the input common-mode range extends 300mV beyond the supply rails.
7 Out B output Output of amplifier B, which the datasheet states swings to within 40mV of the supply rail for light loads.
8 V+ power_in Positive supply rail; the part is specified for a single supply of 4V to 12V or dual supplies of ±2V to ±6V.

CAD (KiCad official)

  • Symbol: OPA2705UA
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: opa2705ua-etched.step / opa2705ua-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); opa2705ua.step / opa2705ua.glb are the bare package body.
