LMH6645MFX

Texas Instruments · Operational Amplifier · SOT-23-5

LMH6645MFX 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 OUTPUT output Signal output, linear output current ±20 mA available at 0.5 V from supply rails, output swing within 20 mV of either supply rail.
2 V- power_in Negative supply input, absolute maximum rating -0.8 V relative to GND, device operates with 2.5 to 12 V supply voltage.
3 +IN input Non-inverting input, input common-mode voltage range 0.3 V beyond V- to 0.3 V beyond V+, input impedance 3 MΩ.
4 -IN input Inverting input, input common-mode voltage range 0.3 V beyond V- to 0.3 V beyond V+, input impedance 3 MΩ.
5 V+ power_in Positive supply input, supply voltage range 2.5 to 12 V relative to V-, typical quiescent supply current 650 μA per channel.

CAD (KiCad official)

  • Symbol: LMH6645MFX
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: lmh6645mfx-etched.step / lmh6645mfx-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lmh6645mfx.step / lmh6645mfx.glb are the bare package body.
