The WM8718 supports PCM data input word lengths from 16 to 32-bits and sampling rates up to 192kHz. The WM8718 consists of a serial interface port, digital interpolation filters, multi-bit sigma delta modulators and differential stereo DAC in a small 20-lead SSOP package or 24-lead QFN package. The WM8718 includes a digitally controllable mute, an attenuate function and zero flag output for each channel. The 3-wire serial control port provides access to a wide range of features including on-chip mute, attenuation and phase reversal. The WM8718 is an ideal device to interface to AC-3™, DTS™, and MPEG audio decoders for surround sound applications, or for use in DVD players including those supporting DVD-A. • 24 bit Stereo DAC • Fully Differential Voltage Outputs • Audio Performance - 111dB SNR (‘A’ weighted @ 48kHz) DAC - -100dB THD • DAC Sampling Frequency: 8kHz - 192kHz • 3 Wire Serial Control Interface • Programmable Audio Data Interface Modes - I2S, Left, Right Justified, DSP - 16/20/24/32 bit Word Lengths • Independent Digital Volume Control on Each Channel with 127.5dB Range in 0.5dB Steps • Independent Zero Flag Outputs • 3.0V - 5.5V Supply Operation • 20-lead SSOP Package or 24-lead QFN Package APPLICATIONS BLOCK DIAGRAM • CD, DVD, and DVD-Audio Players • Home theatre systems www.DataShee•t4U.comProfessional mixing desks W WM8718 CONTROL INTERFACE ZEROFR ZEROFL BCKIN LRCIN DIN AUDIO INTERFACE ATT/ MUTE ATT/ MUTE DIGITAL FILTERS SIGMA DELTA MODULATOR SIGMA DELTA MODULATOR DAC DAC VOUTRP VOUTRN VOUTLP VOUTLN VMID WOLFSON MICROELECTRONICS plc To receive regular email updates, sign up at http://www.wolfsonmicro.com/enews/ Production Data, November 2006, Rev 4.3 Copyright ©2006 Wolfson Microelectronics plc 1 page WM8718 Production Data PIN DESCRIPTION – 20 LEAD SSOP PIN NAME TYPE DESCRIPTION 1 LRCIN Digital Input PCM DAC Sample Rate Clock Input 2 DVDD Supply Positive Digital Supply 3 DGND Supply Ground Digital Supply 4 AVDD Supply Positive Analogue Supply 5 VREFP Supply Positive DAC reference Supply 6 VREFN Supply Negative DAC reference Supply 7 AGND Supply Ground Analogue Supply 8 VMID Analogue Output Mid Rail Decoupling Point 9 VOUTRP Analogue Output Right Channel DAC Output Positive 10 VOUTRN Analogue Output Right Channel DAC Output Negative 11 VOUTLN Analogue Output Left Channel DAC Output Negative 12 VOUTLP Analogue Output Left Channel DAC Output Positive 13 LATCH Digital Input P.U.
