DESCRIPTION

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 8Ω BTL load with

less than 1% distortion (THD+N) from a 5VDC 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.
