WM8593 Datasheet | Wolfson Microelectronics

DESCRIPTION The WM8593 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 volume control and clocking, and a range of input/output channel selection options for flexible routing within current and future audio systems. The WM8593 has an eight stereo input selector which accepts input levels up to 2Vrms. One stereo input can be routed to the ADC. All inputs can be routed to an output selector. The output selector inputs two DAC channels and all analogue bypass inputs, and outputs three independent stereo channels at 2Vrms line level. The DAC channels include independent digital volume control, and all three output channels include analogue volume control. - - - - - WM8593 24-bit 192k Hz 2Vrms Multi-Channel CODEC FEATURES - - - - - Multi-channel CODEC with 8 stereo input selector and 3 stereo output selector 4-channel DAC, 2-channel ADC 8x2Vrms stereo input selector with 8x2 channel analogue bypass to output selector 3x2Vrms stereo output selector 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 rate for ADC and DACs Independent sampling rate for DAC1 and DAC2 DACs sampling frequency 32k Hz - 192k Hz ADC sampling frequency 32k Hz - 96k Hz DAC digital volume control +12d B to -100d B in 0.5d B The WM8593 is ideal for audio applications requiring high steps performance and flexible routing options, including flat panel - ADC analogue volume control from +30d B to -97d B in digital TV and DVD recorder. 0.5d B steps The WM8593 supports up to 2Vrms analogue inputs, 2Vrms .. - Output analogue volume control +6d B to -74d B in 0.5d B outputs, with sample rates from 32k Hz to 192k Hz on the steps with zero cross or soft ramp to prevent pops and DACs, and 32k Hz to 96k Hz on the ADC. clicks The...
