Cirrus Logic’s latest audio codec, the CS42L55, will draw only 5.1mW quiescent power in playback mode.

With a 5x5 mm footprint, the codec features a supply-adjusting bimodal Class H headphone driver and a charge pump architecture with ground-centered outputs.

Based on 24-bit advanced multi-bit Delta-Sigma technology, the CS42L55 operates from a single 1.8 V or 2.5 V power supply and can deliver 1 VRMS line output from a 1.8 V supply. When driving headphones from the same supply it can deliver 17mW per channel of 96dB dynamic range audio.

It also provides a 2:1 stereo input multiplexer and a USB master clock input and supports sample rates up to 48kHz.
