Wolfson Microelectronics is offering a multi-channel audio codec for high definition digital TVs.
The WM8595 has six stereo input selectors and two stereo output selectors, as well as both digital and analogue volume control.
It incorporates a 24-bit ADC and two 24-bit DACs and there is a channel selection capability and various clocking options for digital TV designs.
The DAC audio performance is specified at 100dB SNR, -87dB THD typical, with a sampling frequency of 32kHz to 192kHz.
ADC audio performance is 96dB SNR, -80dB THD typical, with a sampling frequency of 32kHz to 96kHz.
Its digital multiplexer interfaces with multiple digital sources, such as DSP, HDMI or a memory card, and it also features a two-wire or three-wire serial control interface with ‘read back’ and hardware reset, mute and emergency shutdown pins.
The WM8595 is available for sampling now in a 48-pin QFN package.
WM8595 customer evaluation boards are available to aid device evaluation and development.
