LM4864MM from Texas Instruments, in a VSSOP-8. 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 | SHUTDOWN | input | Active-high shutdown input that turns off the amplifier bias circuitry when a logic high is applied, with the trigger point typically half supply, and it must be tied to a definite voltage (ground or VDD). |
| 2 | BYPASS | passive | Half-supply (VDD/2) bypass node that connects to an external capacitor CB, recommended at 1.0 µF or larger for PSRR and click-and-pop performance. |
| 3 | +IN | input | Non-inverting input of the first amplifier. |
| 4 | -IN | input | Inverting input of the first amplifier, where the input resistor Ri and feedback resistor RF set the gain AVD = 2*(RF/Ri). |
| 5 | Vo1 | output | Output of the first amplifier, which drives one side of the bridged load and also feeds the second, unity-gain inverting amplifier. |
| 6 | VDD | power_in | Positive supply pin with an operating range of 2.7V to 5.5V (absolute maximum 6.0V), to be bypassed with a capacitor such as 0.1 µF placed close to the pin. |
| 7 | GND | power_in | Ground pin. |
| 8 | Vo2 | output | Output of the second amplifier, which has a fixed gain of -1 and drives the other side of the bridged load. |
