LM4961 Ceramic Speaker Driver
General Description
The LM4961 is an audio power amplifier primarily designed for driving Ceramic Speaker for applications in Cell Phone and PDAs.
It integrates a boost converter, with variable output voltage, with an audio power amplifier. It is capable of driving 15Vp-p in BTL mode to 2uF+ 30 ohms load, continuous average power, with less than 1% distortion (THD+N) from a 3.2VDC power supply. Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal number of external components. The LM4961 does not require bootstrap capacitors, or snubber circuits therefore it is ideally suited for portable applications requiring high voltage output to drive capacitive loads like Ceramic Speakers. The LM4961 features a low-power consumption shutdown mode. Additionally, the LM4961 features an internal thermal shutdown protection mechanism. The LM4961 contains advanced pop & c
