LMH6629SDE

Texas Instruments · Operational Amplifier · WSON-8-EP(3x3)

LMH6629SDE from Texas Instruments, in a WSON-8-EP(3x3). 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 PD input Power-down control that floats high (device on) when not driven; pulling it low disables the amplifier and puts the output stage in high impedance.
2 FB bidirectional Feedback pin that lets the feedback resistor sit directly next to the inverting input (IN-) to simplify layout.
3 -IN input Inverting input of the voltage-feedback amplifier.
4 +IN input Non-inverting input of the amplifier, with a common-mode range that extends below ground.
5 V- power_in Negative supply; supply voltage (V+ - V-) is 2.7 V to 5.5 V.
6 COMP input Compensation select with an internal pulldown: low (default) gives minimum stable gain of 4 V/V, high gives minimum stable gain of 10 V/V.
7 OUT output Amplifier output, able to drive heavy loads up to ±250 mA and swing to within 0.8 V of the rails.
8 V+ power_in Positive supply; supply voltage (V+ - V-) is 2.7 V to 5.5 V, absolute maximum 6.0 V.
9 DAP passive Exposed pad (from the footprint; not named in the datasheet pin table).
