1 / 2 page www.wolfsonmicro.com ------------------------------------------------------------------------------------ wolfson microelectronics :: leading world experts in the design of signal processing electronics_ Wolfson’s new family of audio ICs for portable applications offers highly integrated, DSP independent solutions that deliver CD quality sound at very low power consumption. The family includes a full audio codec, WM8731, and two DACs, WM8711 and WM8721. All three devices incorporate a powerful headphone amplifier whose output volume can be digitally controlled. Each IC is available as a standard or low voltage part, operating at supply voltages down to 1.42V (digital) and 1.8V (analogue). Using a unique USB clocking scheme, these ICs can generate 44.1kHz, 48kHz, 96kHz and other commonly used sample rates directly from a 12 or 24MHz clock, eliminating the need for a PLL in applications such as MP3 players. The WM8711 and WM8731 are pin-compatible and feature an on-chip clock oscillator to supply the system clock. Wolfson’s portable audio ICs have a very flexible audio interface which can interface to any industry standard DSP or other digital audio chip, thereby providing designers with a higher degree of flexibility. device WM8721 WM8721L WM8711 WM8711L WM8731 WM8731L device type dac dac (low voltage) dac dac (low voltage) codec codec (low voltage) digital supply voltage 1.42V – 3.6V 1.42V – 3.6V 1.42V – 3.6V 1.42V – 3.6V 1.42V – 3.6V 1.42V – 3.6V analogue supply voltage 2.7V – 3.6V 1.8V – 3.6V 2.7V – 3.6V 1.8V – 3.6V 2.7V – 3.6V 1.8V – 3.6V analogue line-in no no yes yes yes yes microphone input no no no no yes yes on-chip clock generator no no yes yes yes yes package 20-pin SSOP 20-pin SSOP 28-pin SSOP 28-pin SSOP 28-pin SSOP 28-pin SSOP ----------------------------------------------------------------------------------------------------------------------------------------------------- ----------------------------------------------------------------------------------------------------------------------------------------------------- ------------------------------------------------------------------------------------------------- AUDIO DACs AND CODECS FOR BATTERY-POWERED APPLICATIONS productbenefits portable digital audio solutions WM8711 WM8721 WM8731 long battery life cd sound quality powerful headphone amplifier highly integrated solution dsp independent |
