The LM4962 is an audio power amplifier primarily designed for driving Ceramic Speaker for applications in Cell Phones, Smart Phones, PDA's and other portable applications. It is capable of driving 15Vpp (typ) BTL with less than 1% THD+N from a 3.2VDC power supply. The LM4962 features and low power consumption shutdown mode, an internal thermal shutdown protection mechanism, along with over current protection (OCP) and over voltage protection (OVP). Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal number of external components. The LM4962 does not require bootstrap capacitors, or snubber circuits. The LM4962 also features a Band-Switch function which allows the user to use one amplifier device for both receiver (earpiece) mode and ringer/loudspeaker mode. The LM4962 contains advanced pop & click circuitry that eliminates noises which would otherwise occur during turn-on and turn-off transitions. Additionally, the internal boost converter features a soft-start function.
