WM8960 Overview

The WM8960 is a low power, high quality stereo CODEC designed for portable digital audio applications. 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 8Ω 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.

The WM8960 has a configurable digital audio interface where ADC data can be read and digital audio playback data fed to the DAC. The WM8960 is controlled by writing to registers through a 2-wire serial control interface. A control word consists of 16 bits. The WM8960 operates as a slave device only. The WM8960 has three control registers that allow users to select which functions are active.

This article provides you with a basic overview of the WM8960 Stereo CODEC, including its pin descriptions, features and specifications, etc., to help you quickly understand what WM8960 is.

Frequently Asked Questions

How many stereo analog input channels does WM8960 have?

The WM8960 has three flexible stereo analogue input channels which can be configured as line inputs, differential microphone inputs or single-ended microphone inputs. Line inputs and microphone PGA outputs can be routed to the hi-fi ADCs or directly to the output mixers via a bypass path.

What is the use of automatic level control in WM8960? And how does that happen?

The WM8960 has an automatic level control that aims to keep a constant recording volume irrespective of the input signal level. This is achieved by continuously adjusting the PGA gain so that the signal level at the ADC input remains constant.

Can the digital 3D enhancement options available for WM8960 be used for recording?

The WM8960 has a digital 3D enhancement option to artificially increase the separation between the left and right channels. This effect can only be used for playback, not for record.

Under what circumstances can the timeout circuit in WM8960 automatically update the volume?

If there is a long period where no zero-crossing occurs, a timeout circuit in the WM8960 will automatically update the volume. The volume updates will occur between one and two timeout periods, depending on when the volume update bit is set.

What is the principle of protecting WM8960 from overheating?

The speaker and headphone outputs can drive very large currents. To protect the WM8960 from overheating a thermal shutdown circuit is included and is enabled by default. If the device temperature reaches approximately 1500℃ and the thermal shutdown circuit is enabled the speaker and headphone amplifiers will be disabled. This feature can be disabled to save power when the device is in standby mode.
