WM8594
WM8594 is Multi-Channel CODEC manufactured by Wolfson Microelectronics.
DESCRIPTION
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 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 WM8594 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 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.
