WM8523GEDT

Overview

The WM8523GEDT is a stereo digital-to-analog converter (DAC) featuring an integral charge pump and software control interface. It provides 2Vrms ground-referenced line driver outputs using a single 3.3V power supply rail. The device incorporates a DC servo to eliminate coupling capacitors and suppress power-on pops. It supports sampling rates from 8kHz to 192kHz with I2C/SPI or hardware control interfaces. Key electrical parameters include a 106dB A-weighted SNR, -89dB THD at -1dBFS, and a maximum 1mV DC offset on line outputs. The component is housed in a 20-lead TSSOP package.

Feature Summary

High-performance stereo DAC with integrated charge pump for 2Vrms output
Audio performance: 106dB SNR (A-weighted), -89dB THD, 120dB mute attenuation
Supports digital audio formats: Left Justified, Right Justified, I2S, DSP Mode A/B
Digital volume control ranging from -100dB to +12dB

Applications

Set Top Box
Digital TV
DVD Players
Games Consoles
A/V Receivers

Procurement Notes

Verify the ordering code matches the specific package variant required. The standard part number WM8523GEDT corresponds to the tube version, while WM8523GEDT/R indicates tape and reel packaging with a quantity of 2000 units. Confirm the temperature range is -40°C to +85°C for both variants. Ensure the source document aligns with the specific revision level needed for design compatibility.

Selection Notes

Select this component for applications requiring a single 3.3V supply and ground-referenced outputs without external coupling capacitors. It is suitable for systems needing digital volume control and de-emphasis support. Verify that the host processor can interface via I2C, SPI, or hardware pins. Ensure the load impedance is compatible with the specified 1kΩ minimum for optimal SNR performance.

Part Context

The WM8523GEDT belongs to the Cirrus Logic WM8523 series of stereo DACs. It is functionally identical to the WM8523GEDT/R, differing only in packaging format (tube vs. tape and reel). Both variants share the same pinout, electrical characteristics, and thermal specifications within the industrial temperature range.
