The LM4962 is an audio power amplifier primarily designed for driving Ceramic Speaker for applications in Cell Phones, Smart Phones, PDA’s, portable DVD, digital still camera/camcorders. This IC features low current shutdown mode, low quiescent current, over-current protection, over-Voltage Protection, leakage cut switch (SW-LEAK), mono 15Vp-p BTL output, RL = 2μF+9.4Ω, f = 1kHz, 1% THD+N, etc. 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.
This datasheet contains detail information about LM4962 including general description, key features and specifications, applications, connection diagram, block diagram, typical application, absolute maximum ratings, operating ratings, electrical characteristics, typical performance characteristics, application information and physical dimensions data.
