WM8599 Datasheet | Wolfson Microelectronics

DESCRIPTION The WM8599 is a high performance multi-channel audio CODEC with flexible input/output selection and digital and analogue volume control. Features include a 24-bit stereo ADC with digital gain control, two 24-bit DACs with independent digital volume control, and a range of input/output channel selection options with analogue volume control, for flexible routing within current and future audio systems. The WM8599 accepts five stereo audio inputs at line levels up to 2Vrms. One stereo input can be routed to the ADC. All inputs can be routed to the output. The WM8599 outputs three stereo audio channels at line levels up to 2Vrms, which can be selected from any of the analogue inputs and DAC outputs. The DAC channels include independent digital volume control, and all three stereo output channels include analogue volume control with soft ramp. The WM8599 supports up to 2Vrms analogue inputs, 2Vrms outputs, with sampling rates from 32k Hz to 192k Hz for the DACs, and 32k Hz to 96k Hz for the ADC. The WM8599 is ideal for audio applications requiring high performance and flexible routing options, including flat panel digital TV and DVD recorder. The device is controlled via a serial interface with support for 2-wire control with readback. Control of mute, powerdown and reset can also be achieved by pin selection. The WM8599 is available in a 48-lead TQFP package. 24-bit 192k Hz 2Vrms Multi-Channel CODEC FEATURES - - - - Multi-channel CODEC with 5 stereo input selector and 3 stereo output selector 4-channel DAC, 2-channel ADC Five stereo 2Vrms stereo inputs with analogue bypass to three stereo 2Vrms outputs Audio performance DAC: 100d B SNR typical (‘A’ weighted @ 48k Hz) - - - - - - - - - - - - DAC: -90d B THD typical ADC: 100d B SNR typical (‘A’ weighted @ 48k Hz) ADC: -90d B THD typical Independent sampling rates for ADC and DACs DACs sampling frequency 32k Hz to 192k Hz ADC sampling frequency 32k Hz to 96k Hz ADC digital gain control: +30d B to -97d B DAC digital...
