LM4864MMX 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 | Shutdown control that turns off the amplifier bias circuitry when a logic high is applied (trigger point typically half supply), and it should be tied to a definite voltage (VDD for lowest idle current, 0.7 µA typ at 5V). |
| 2 | BYPASS | passive | Half-supply (VDD/2) bypass pin that connects to an external capacitor CB (1.0 µF recommended) for half-supply filtering, PSRR and turn-on click and pop performance. |
| 3 | +IN | input | Non-inverting input of the first amplifier, which connects to the bypass node in the typical application circuit. |
| 4 | -IN | input | Inverting input of the first amplifier, which receives the audio input through Ci and Ri and sets the gain with RF (AVD = 2*RF/Ri). |
| 5 | Vo1 | output | Output of the first amplifier, which drives one side of the bridged load. |
| 6 | VDD | power_in | Positive supply input, operating range 2.7V to 5.5V (6.0V absolute maximum), which needs a bypass capacitor (CS 0.1 µF typical) placed close to the pin. |
| 7 | GND | power_in | Ground pin, the reference for all voltages. |
| 8 | Vo2 | output | Output of the second amplifier (unity-gain inverting stage), which drives the other side of the bridged load 180° out of phase with Vo1. |
