General 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 pop & click 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.

Note: The Early Failure Rates were calculated as point estimates. The Long Term Failure Rates were calculated
at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress
temperature of 150°C to an application temperature of 55°C.
