WM8960

DESCRIPTION

The WM8960 is a low power, high quality stereo CODEC

designed for portable digital audio applications.

Stereo class D speaker drivers provide 1W per channel into 8



loads with a 5V supply. Low leakage, excellent PSRR and

pop/click suppression mechanisms also allow direct battery

connection to the speaker supply. Flexible speaker boost

settings allow speaker output power to be maximised while

minimising other analogue supply currents.

A highly flexible input configuration for up to three stereo

sources is integrated, with a complete microphone interface.

External component requirements are reduced as no separate

microphone, speaker or headphone amplifiers are required.

Advanced on-chip digital signal processing performs automatic

level control for the microphone or line input.

Stereo 24-bit sigma-delta ADCs and DACs are used with low

power over-sampling digital interpolation and decimation filters

and a flexible digital audio interface.

The master clock can be input directly or generated internally by

an onboard PLL, supporting most commonly-used clocking

schemes.

The WM8960 operates at analogue supply voltages down to

2.7V, although the digital supplies can operate at voltages down

to 1.71V to save power. The speaker supply can operate at up

to 5.5V, providing 1W per channel into 8

 loads. Unused

functions can be disabled using software control to save power.

The WM8960 is supplied in a very small and thin 5x5mm QFN

package, ideal for use in hand-held and portable systems.
