LMH6639MF

Texas Instruments · Operational Amplifier · SOT-23-6

LMH6639MF from Texas Instruments, in a SOT-23-6. 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 OUTPUT output Rail-to-rail amplifier output that swings to within about 30mV of either supply rail with 110mA linear output current.
2 V- power_in Negative supply (ground in single-supply use); the input common mode range extends 0.2V below this pin.
3 +IN input Non-inverting input of the voltage feedback amplifier, protected by anti-parallel diodes and a series resistor across the inputs.
4 -IN input Inverting input of the voltage feedback amplifier, protected by anti-parallel diodes and a series resistor across the inputs.
5 SD input Shutdown input that disables the amplifier when pulled below a threshold of V+ - 1.67V (±5V supplies), with off-mode supply current of 400μA at 5V.
6 V+ power_in Positive supply; the input common mode range extends to within 1V of this pin and the part is characterized for 3V, 5V and ±5V.

CAD (KiCad official)

  • Symbol: LMH6639MF
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: lmh6639mf-etched.step / lmh6639mf-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lmh6639mf.step / lmh6639mf.glb are the bare package body.
