LM4863M

HGSEMI · Audio Amplifiers · SOP-16

LM4863M from HGSEMI, in a SOP-16. 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 control; taking it to VDD puts the part in low-power shutdown (0.7µA typ), and it should be tied to GND for normal operation or never left floating.
2 GND power_in Ground.
3 +OUTA output Channel A non-inverting bridge output; the speaker load connects between -OUTA and +OUTA.
4 VDD power_in Positive supply, 2.0V to 5.5V operating range (6.0V absolute maximum).
5 -OUT A output Channel A inverting bridge output; the speaker load connects between -OUTA and +OUTA.
6 -IN A input Channel A inverting input, connected through Ri and Ci with feedback resistor Rf to set closed-loop gain.
7 GND power_in Ground.
8 +IN A input Channel A non-inverting input.
9 +IN B input Channel B non-inverting input.
10 BYPASS passive Half-supply bias node; connect a capacitor CB (1.0µF typical) to ground to filter the VDD/2 reference and improve PSRR.
11 -IN B input Channel B inverting input, connected through Ri and Ci with feedback resistor Rf to set closed-loop gain.
12 -OUT B output Channel B inverting bridge output; the speaker load connects between -OUTB and +OUTB.
13 VDD power_in Positive supply, 2.0V to 5.5V operating range (6.0V absolute maximum).
14 +OUT B output Channel B non-inverting bridge output; the speaker load connects between -OUTB and +OUTB.
15 GND power_in Ground.
16 HP-IN input Headphone sense input; 4V to VDD disables Amp2A and Amp2B (single-ended headphone mode), and below 0.8V selects bridged mode.
