LM4953 Ground-Referenced, Ultra Low Noise, Ceramic Speaker Driver
General Description
The LM4953 is an audio power amplifier designed for driving Ceramic Speaker in portable applications.
When powered by a 3.6V supply, it is capable of forcing 12.6Vpp across a 2µF + 30 bridge-tied-load (BTL) with less than 1% THD+N. Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components. The LM4953 does not require bootstrap capacitors, or snubber circuits. Therefore it is ideally suited for display applications requiring high power and minimal size. The LM4953 features a low-power consumption shutdown mode. Additionally, the LM4953 features an internal thermal shutdown protection mechanism. The LM4953 contains advanced pop & click circuitry that eliminates noises which would otherwise occur during turn-on and turn-off transitions. The LM4
