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). |
