LM4915 Datasheet Pseudo-differential Mono Headphone Amplifier

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM4915 Pseudo-Differential Mono Headphone Amplifier with Fixed 6dB Gain May 2003 LM4915 Pseudo-Differential Mono Headphone Amplifier with Fixed 6dB.

General Description

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.

Key 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. Key Specifications n n n n Improved PSRR at 217Hz and 1kHz 75dB (typ) Power Output at 5.0V & 1%.
