LM4817 1W Stereo Audio Amplifier Plus Adjustable Output Limiter Plus Adjustable LDO
General Description
The LM4817 combines a bridge-connected (BTL) stereo audio power amplifier with a low dropout voltage
regulator (LDO).
The audio amplifier delivers 1.
0W to a 8Ω load with a less than 1.
0% THD+N while operating on a 5V power supply.
With VLIM set to 1.
0V, the amplifier outputs are clamped to 6Vp-p, ± 800mV.
With the LM4817’s adjustable low-dropout (LDO) CMOS linear
regulator delivers an output current of up to 300mA, has shutdown mode (1nA, typ) low quiescent current (90µA, t...
