WM8860

Multi-Channel High Definition Audio CODEC

DESCRIPTION

FEATURES



Multi-channel High Definition Audio CODEC

Fully compatible with Intel High Definition Audio Revision 1.0

4-Channel DAC, 4-channel ADC

DAC sampling frequency 8kHz - 192kHz

ADC sampling frequency 8kHz - 96kHz

DAC Performance:

The WM8860 is

a high performance multi-channel audio

CODEC designed for high performance portable PC audio

systems. The device offers full compatibility with the Intel High

Definition Audio (HDA) specification revision 1.0, allowing

seamless integration with industry-standard HDA controllers.

The WM8860 has two high performance stereo DACs to enable

four channels of high definition audio. A high-performance

ground-referenced stereo headphone amplifier utilises advanced

charge pump and DC servo technology to minimise system cost

and space without compromise on audio quality. A balanced

line output, which can provide a differential connection to an

external speaker amplifier, is also provided and enables

common mode noise rejection when these traces are routed

across a PCB.

SNR 108dB (‘A’ weighted)

SNR 105dB (non weighted)

THD -96dB (at 0dBFS)



ADC Performance:

SNR 105dB (‘A’ weighted)

SNR 102dB (non weighted)

THD -95dB (at -1dBFS)



Ground-referenced stereo headphone driver

Differential line inputs/outputs

Stereo microphone interface with integrated pre-amp

Multi-channel digital microphone interface

IEC-60958-3 compatible S/PDIF transmitter

Jack detect and load impedance sensing

Beep generator

GPIO functionality

IEEE-754 Single precision 32-bit floating point support

Power supplies

The WM8860 also has two high performance stereo ADCs to

provide Hi-Fi quality analogue line-in and microphone input

digitisation. A low noise microphone bias with programmable

output voltage is provided. Additionally, the CODEC contains a

digital microphone interface capable of supporting up to four

independent digital microphones. One differential stereo input is

provided for line level signals, while one pseudo-differential

stereo input with integrated microphone preamplifier is provided.

Digital core:

Digital buffer: 2.97V – 3.63V

Analogue: 4.5V – 5.25V

Charge pump: 4.5V – 5.25V

1.62V – 1.98V

The WM8860 also contains a S/PDIF transmitter which is fully

compatible with IEC-60958-3. Two dedicated GPIO pins are

provided, enabling control of external amplifiers or other

additional system components.



48-pin 7mm x 7mm QFN package

The WM8860 is supplied in a small 48-pin QFN package.

APPLICATIONS



High performance PC audio

All-in-one desktop PC

Notebook PC
