LM4871MM

Texas Instruments · Audio Amplifiers · VSSOP-8

LM4871MM 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 (VDD) is applied, giving 0.6µA typical shutdown current; it must be tied to a definite voltage.
2 BYPASS passive Half-supply bypass node that connects to an external capacitor CB (1.0µF recommended) to ground for PSRR and turn-on click and pop performance.
3 +IN input Non-inverting amplifier input.
4 -IN input Inverting amplifier input that sets the closed-loop gain through Ri and Rf, where AVD = 2*(Rf/Ri).
5 Vo1 output Bridged amplifier output 1, driving one side of the load, 180° out of phase with Vo2.
6 VDD power_in Positive supply input for a supply range of 2.0V to 5.5V (absolute maximum 6.0V), which needs a bypass capacitor placed close to the pin.
7 GND power_in Ground connection.
8 Vo2 output Bridged amplifier output 2, driving the other side of the load, 180° out of phase with Vo1.
