DESCRIPTION
Stereo 24-bit multi-bit sigma delta DACs are used with oversampling digital interpolation filters. Digital audio input word lengths from 16-32 bits and sampling rates from 8kHz to 96kHz are supported. Stereo audio outputs are buffered for driving headphones from a programmable volume control, line level outputs are also provided along with anti-thump mute and power up/down circuitry. The device is controlled via a 2 or 3 wire serial interface. The interface provides access to all features including volume controls, mutes, de-emphasis and extensive power management facilities. The device is available in an ultrasmall 24-lead QFN (4x4x0.9 mm Body) package. A USB clocking mode is provided where all audio rates can be derived from a single 12MHz or 24MHz MCLK, saving on the need for a PLL or multiple crystals. BLOCK DIAGRAMFEATURES
