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.

Key Features

  • a low-power consumption shutdown mode. Additionally, the LM4961 features an internal thermal shutdown protection mechanism. The LM4961 contains advanced pop & click circuitry that eliminates noises which would otherwise occur during turn-on and turn-off transitions. The LM4961 is unity-gain stable and can be configured by external gain-setting resistors. Key Specifications n Quiescent Power Supply Current n Voltage Swing in BTL at 1% THD n Shutdown current 7mA (typ) 15Vp-p (typ) 0.1µA (typ) Fe.
