LM4954 - HIgh Voltage 3 Watt Audio Power Amplifier

Datasheet Summary

Description

The LM4954 is an audio power amplifier primarily designed for demanding applications in mobile phones and other portable communication device applications.

It is capable of delivering 2.4 Watts of continuous average power to an 8Ω BTL load with less than 1% THD+N from a 7VDC power supply.

Features

a low-power consumption global shutdown mode which is achieved by driving the shutdown pin with logic low. Additionally, the LM4954 features an internal thermal shutdown protection mechanism. The LM4954 contains advanced pop & click circuitry which eliminates noises that would otherwise occur during turn-on and turn-off transitions. The LM4954 is unity-gain stable and can be configured by external gain-setting resistors. Key Specifications j Wide Power Supply Voltage Range j Output Power: VDD.

It is capable of delivering 2.4 Watts of continuous average power to an 8Ω BTL load with less than 1% THD+N from a 7VDC power supply. Boomer audio power amplifiers are designed specifically to provide high quality output power with a minimal number of external components. The LM4954 does not require output coupling capacitors or bootstrap capacitors, and therefore is ideally suited for lower-power portable applications where minimal space and power consumption are primary requirements.
