Description

The CS42L50 is a highly integrated, 24-bit, 96 kHz audio codec.

This device is based on delta-sigma modulation allowing infinite adjustment of the sample rate between 8 kHz and 100 kHz simply by changing the master clock frequency.

The CS42L50 contains a 2:1 stereo mux, programmable analog gain control, and digital attenuation on the analog inputs. The output D/A converters include digital bass and treble boost, dynamic range compression, limiting, mixing, volume control and de-emphasis.

The CS42L50 operates from a +1.8 V to +3.3 V supply.

These features are ideal for portable MP3 and MD recorders, CD and DVD recorders, digital camcorders, and other portable systems that require extremely low power consumption in a minimal amount of space.
