LM4702 Audio Power Amplifier Series Stereo High Fidelity 200 Volt Driver with Mute
General Description
The LM4702 is a high fidelity audio power amplifier driver designed for demanding consumer and pro-audio applications.

Amplifier output power may be scaled by changing the supply voltage and number of output devices. The LM4702 is capable of delivering in excess of 300 watts per channel single ended into an 8 ohm load in the presence of 10% high line headroom and 20% supply regulation. The LM4702 includes thermal shut down circuitry that activates when the die temperature exceeds 150°C. The LM4702's mute function, when activated, mutes the input drive signal and forces the amplifier output to a quiescent state. The LM4702 is available in 3 grades that span a wide range of applications and performance levels. The LM4702C is targeted at high volume applications. The LM4702B includes a higher voltage rating along with
