描述

The WM8594 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 with analogue volume control for flexible routing within current and future audio systems.

The WM8594 has a five 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 WM8594 outputs three stereo audio channels at line levels up to 2Vrms, which can be selected from any of the analogue inputs and DAC outputs. Additionally, one stereo output is available with a headphone driver. The DAC channels include independent digital volume control, and all three stereo output channels include analogue volume control with soft ramp.

The WM8594 supports up to 2Vrms analogue inputs, 2Vrms outputs, with sampling rates from 32kHz to 192kHz for the DACs, and 32kHz to 96kHz for the ADC.

The WM8594 is controlLED via a serial interface with support for 2-wire and 3-wire control with full readback. Control of mute, powerdown and reset can also be achieved by pin selection.

The WM8594 is ideal for audio applications requiring high performance and flexible routing options, including flat panel digital TV and DVD recorder.

The WM8594 is available in a 48-lead TQFP package.
