LMH6642MFX

Texas Instruments · Operational Amplifier · SOT-23-5

LMH6642MFX from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUTPUT output Amplifier output. Rail-to-rail output stage swings to within 40 mV of either supply rail and can source/sink up to ~75 mA of linear output current (short-circuit current +115 to 145 mA).
2 V- power_in Negative supply rail. Connect to ground for single-supply operation or to a negative rail for split-supply operation. Total supply voltage (V+ − V−) must be between 2.7 V and 12.8 V (absolute max 13.5 V).
3 +IN input Non-inverting input. Input common-mode voltage range extends from 0.5 V below V− to within 1 V of V+. Differential input voltage is limited to ±2.5 V absolute maximum; input current is limited to ±10 mA.
4 -IN input Inverting input. Input common-mode voltage range extends from 0.5 V below V− to within 1 V of V+. Differential input voltage is limited to ±2.5 V absolute maximum; input current is limited to ±10 mA.
5 V+ power_in Positive supply rail. Total supply voltage (V+ − V−) must be between 2.7 V and 12.8 V (absolute max 13.5 V). Bypass locally with a decoupling capacitor to V−/ground.
