WM8595: 24-bit 192kHz 2Vrms Multi-Channel CODEC
The WM8595 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 WM8595 h
asa six stereo input selector which accepts input levels up to 2Vrms. One stereo input can be selected through an input mux to be routed through to the ADC.
The WM8595 outputs two stereo audio channels at line levels up to 2Vrms, driven from independent DACs. The DAC channels include independent digital volume control, and both stereo output channels include analogue volume control with soft ramp.
The WM8595 supports up to 2Vrms analogue inputs, 2Vrms outputs, with sample rates from 32kHz to 192kHz on the DACs, and 32kHz to 96kHz on the ADC.
The WM8595 is controlled via a serial interface with support for 2-wire and 3-wire control with full readback. Control of mute, emergency shutdown and re
setcan also be achieved
by
pinselection.
