LM4925 Datasheet (National Semiconductor) - 2 Cell/ Single Ended Output 40mW Stereo Headphone Audio Amplifier

LM4925, 2 Cell/ Single Ended Output 40mW Stereo Headphone Audio Amplifier

The unity gain stable LM4925 is both a mono differential output (for BTL operation) audio amplifier and a Single Ended (SE) stereo headphone amplifier.

Operating on a single 3V supply, the mono-BTL mode delivers 410mW into an 8Ω load at 1% THD+N.

In Single Ended stereo headphone mode, the amplifier

LM4925 Features

* circuitry that reduces output transients (“clicks” and “pops”) during device turn-on and turn-off, an externally controlled, low-power consumption, active-low shutdown mode, and thermal shutdown. Boomer audio power amplifiers are designed specifically to use few external components and provide high
