The LM4995 is an audio power amplifier primarily designed for demanding applications in mobile phones and other portable communication device applications. It is capable of delivering 1.2W of continuous average power to an 8? BTL load with less than 1% distortion (THD+N) from a 5V_DC power supply.

Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components. The LM4995 does not require output coupling capacitors or bootstrap capacitors, and therefore is ideally suited for mobile phone and other low voltage applications where minimal power consumption is a primary requirement.

The LM4995 features a low-power consumption shutdown mode, which is achieved by driving the shutdown pin with logic low. Additionally, the LM4995 features an internal thermal shutdown protection mechanism.

The LM4995 contains advanced click and pop circuitry which eliminates noise which would otherwise occur during turn-on and turn-off transitions.

The LM4995 is unity-gain stable and can be configured by external gain-setting resistors.
