WM8523

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

DESCRIPTION

FEATURES

•

High performance stereo DAC with ground referenced line

driver

Audio Performance

The WM8523 is a stereo DAC with integral charge pump

and software control interface. This provides 2Vrms line

driver outputs using a single 3.3V power supply rail.

•

−

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

20-lead TSSOP or 24-lead QFN packages

Operating temperature range: -40°C to 85°C

The device supports all common audio sampling rates

between 8kHz and 192kHz using all common MCLK fs

rates. Master and Slave modes are available and de-

emphasis is also supported.

APPLICATIONS

The WM8523 has a 3.3V tolerant digital interface, allowing

logic up to 3.3V to be connected.

•

Consumer digital audio applications requiring 2Vrms output

−

Set Top Box

Digital TV

DVD Players

Games Consoles

A/V Receivers

The device is available in a 20-lead TSSOP or 24-lead

QFN.
