The LM4915 is a pseudo-differential audio power amplifier primarily designed for
demanding applications in mobile phones and other portable audio device applications with mono
headphones. It is capable of delivering 90 miliwatts of continuous average power to a 32Ω BTL load
with less than 1% distortion (THD+N) from a 3VDC power supply.
Boomer audio power amplifiers were designed specifically to provide high quality output
power with a minimal amount of external components. The LM4915 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 LM4915 features a low-power consumption shutdown mode. To facilitate this, Shutdown
may be enabled by driving the shutdown pin low. Additionally, the LM4915 features an internal
thermal shutdown protection mechanism.
The LM4915 contains advanced pop & click circuitry which virtually eliminates noises
which would otherwise occur during turn-on and turn-off transitions.
The LM4915 has an internally fixed gain of 6dB.
