WM8533

24-bit 192kHz Stereo DAC with 2Vrms Ground Referenced Line Output

DESCRIPTION

FEATURES

The WM8533 is a stereo DAC with integral charge pump and

software control interface. This provides 2Vrms line driver

outputs using a 3.3V power supply rail.



High performance stereo DAC with ground referenced line

driver

Audio performance





106dB SNR (‘A-weighted’)

-89dB THD @ -1dBFS

The device features ground-referenced outputs and the use

of a DC servo to eliminate the need for line driving coupling

capacitors and effectively eliminate power on pops and

clicks.



Digital volume control ranging from -100dB to +12dB

120dB mute attenuation

All common sample rates from 8kHz to 192kHz supported

I²C/SPI compatible and hardware control modes

Data formats: LJ, RJ, I²S, DSP

The device is controlled and configured either via the

I2C/SPI compliant serial control interface or a hardware

control interface.

De-emphasis supported

Maximum 1mV DC offset on line outputs

Pop/click suppressed power up/down sequencer

AVDD and LINEVDD +3.3V ±10% allowing single supply

DBVDD supply supports +1.8V or +3.3V digital I/O

1.842 x 1.772mm 20-ball WCSP

The device supports all common audio sampling rates

between 8kHz and 192kHz using all common MCLK / fs

ratios. Master and slave modes are available and de-

emphasis is also supported.

The WM8533 has a 1.8 to 3.3V tolerant digital interface,

allowing logic up to 3.3V to be connected.

The device is available in a 1.842 x 1.772mm 20-ball WCSP.

APPLICATIONS



Consumer digital audio applications requiring 2Vrms output



Set Top Box

Digital TV

DVD Players

Games Consoles

A/V Receivers
