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, progra mmable 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 re- corders, CD and DVD recorders, digital camcorders, and other portable systems that require extremely low power consumption in a minimal amount of space.
