The LM4953 is an audio amplifier that can drive a ceramic speaker with a charge pump, requiring only eight external components. The LM4953 is available in a 3mm x 4mm package, but with an audio amplifier and charge pump built in, it can boost the 3.6V supply voltage and provide a peak-to-peak voltage of up to 12.6V for a 2uF + 30W bridge load. Wave distortion and noise will not exceed 1%.
Both speaker drivers feature a low-power shutdown mode and internal thermal shutdown protection without the need for a startup capacitor or transient voltage suppression circuit, as well as a “switch/switch†noise suppression circuit. Their unity gain is very stable and can be configured with an external gain setting resistor.
The LM4962 is 5mm x 5mm and has a built-in boost converter that drives the capacitive load of the ceramic speaker and also drives the stereo speakers. In addition, the chip has an audio power amplifier that supports mono ceramic speakers. It uses a 3.2V DC power supply to provide 15V peak-to-peak voltage for bridged loads (BTL) without total harmonic distortion and noise (THD+N) of more than 1%. In addition, the LM4962 chip features overcurrent protection and overvoltage protection to protect the boost converter. The built-in DC/DC converter features a soft-start function.
