SPWLM386D

Low Voltage Audio Power

Amplifier

* Wide Supply Voltage Range: 4V~12V

* Low Quiescent Current Drain: 4mA

* Voltage Gains: 20~200

* Low Distortion: 0.2% ( Av=20, Vs=6V, RL=8

, Po=125mW, f=1 kHz)

* Self-Centering Output Quiescent Voltage

* Battery Operation

* Minimum External Parts

* Ground Referenced Input

Features

The SPWLM386D is a power amplifier, designed for use in low

voltage consumer applications. The gain is internally set to 20

to keep external part count low, but the addittion of an external

resistor and capacitor between pin 1 and pin 8 will increase the

gain to any value up from 20 to 200. The input are ground

referenced while the output automatically biases to one-half the

supply voltage. The quiescent power drain is only 24 millwatts

when operating from a 6 voltage supply, marking the SPWLM386D

ideal for battery operation.
