OPA704UA

Texas Instruments · Operational Amplifier · SOIC-8

OPA704UA 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.
2 -In input Inverting input of the amplifier; input range extends 0.3V beyond the supply rails, with input current limited to 10mA if signals swing further.
3 +In input Non-inverting input of the amplifier; input range extends 0.3V beyond the supply rails, with input current limited to 10mA if signals swing further.
4 V- power_in Negative supply (ground in single-supply use); supply range V+ to V- is 4V to 12V specified, 13.2V absolute maximum.
5 NC unconnected No internal connection.
6 Out output Amplifier output with rail-to-rail swing to within 40mV of the rail, short-circuit current of ±40mA.
7 V+ power_in Positive supply; supply range V+ to V- is 4V to 12V specified, 13.2V absolute maximum.
8 NC unconnected No internal connection.

CAD (KiCad official)

  • Symbol: OPA704UA
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: opa704ua-etched.step / opa704ua-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); opa704ua.step / opa704ua.glb are the bare package body.
