LMH6642QMF

Texas Instruments · Operational Amplifier · SOT-23-5

LMH6642QMF 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 Amplifier output, capable of about 75mA linear output current with swing to within 40mV of the supply rails.
2 V- power_in Negative supply; total supply voltage (V+ - V-) must be 2.7V to 10V (13.5V absolute maximum).
3 +IN input Non-inverting input, with common-mode range extending 0.5V below V- to 1V above V+.
4 -IN input Inverting input of the amplifier.
5 V+ power_in Positive supply; total supply voltage (V+ - V-) must be 2.7V to 10V (13.5V absolute maximum).
