OPA843ID

Texas Instruments · Operational Amplifier · SOIC-8

OPA843ID 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 marks this pin as NC (no connection).
2 Inverting Input input Inverting input of the op amp; the differential input voltage is limited to ±1.2V absolute maximum.
3 Noninverting Input input Noninverting input of the op amp; common-mode input range is ±3.2V min at 25°C with VS = ±5V.
4 -VS power_in Negative power supply; specified at −5V with a minimum operating voltage of ±4V and maximum operating voltage of ±6V (absolute maximum supply ±6.5V).
5 NC unconnected No connection; the datasheet marks this pin as NC (no connection).
6 Output output Output of the amplifier; output current is ±100mA min at VO = 0V (25°C).
7 +VS power_in Positive power supply; specified at +5V with a minimum operating voltage of ±4V and maximum operating voltage of ±6V (absolute maximum supply ±6.5V).
8 NC unconnected No connection; the datasheet marks this pin as NC (no connection).

CAD (KiCad official)

  • Symbol: OPA843ID
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: opa843id-etched.step / opa843id-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); opa843id.step / opa843id.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
