LMH6639MFX

Texas Instruments · Operational Amplifier · SOT-23-6

LMH6639MFX 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 swinging to within 30mV of either supply rail with 110mA linear output current.
2 V- power_in Negative supply; the input common mode range extends to 0.2V below V-.
3 +IN input Non-inverting input; common mode range is -0.2V to within 1V of V+ (-0.2V to 4V at 5V supply).
4 -IN input Inverting input, protected by two anti-parallel diodes and a series resistor across the inputs.
5 SD input Shutdown control input; the device shuts down below a threshold of about V+ - 1.67V (supply current 400µA off mode at 5V).
6 V+ power_in Positive supply; fully characterized for 3V, 5V and ±5V operation.
