OPA657N

Texas Instruments · FET Input Amplifiers · SOT-23-5

OPA657N from Texas Instruments, in a SOT-23-5. 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 VOUT output Output of the amplifier, specified with a high output current of 70 mA in the datasheet features list.
2 -VS power_in Negative power supply; total supply voltage is limited to ±6.5 V absolute maximum, with 8 V to 12 V total recommended.
3 VIN+ power_in Noninverting input; input voltage must stay between -VS and +VS per the absolute maximum ratings.
4 VIN- power_in Inverting input; input voltage and differential input voltage are limited to -VS to +VS per the absolute maximum ratings.
5 +VS power_in Positive power supply; total supply voltage is limited to ±6.5 V absolute maximum, with 8 V to 12 V total recommended.

CAD (KiCad official)

  • Symbol: OPA657N
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: opa657n-etched.step / opa657n-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); opa657n.step / opa657n.glb are the bare package body.
