WM9711L

Low Power Audio CODEC for Portable Applications

DESCRIPTION

FEATURES

• AC’97 Rev 2.2 compatible stereo codec

- DAC SNR 94dB, THD –87dB

The WM9711L is a highly integrated input / output device

designed for mobile computing and communications. The

device can connect directly to mono or stereo microphones,

stereo headphones and a mono speaker, reducing total

component count in the system. Additionally, phone input

and output pins are provided for seamless integration with

wireless communication devices.

- ADC SNR 92dB, THD –87dB

- Variable Rate Audio, supports all WinCE sample rates

- Tone Control, Bass Boost and 3D Enhancement

• On-chip 45mW headphone driver

• On-chip 400mW mono speaker driver

• Stereo, mono or differential microphone input

- Automatic Level Control (ALC)

• Auxiliary mono DAC (ring tone or DC level generation)

• Seamless interface to wireless chipset

• Up to 5 GPIO pins

The WM9711L also offers five GPIO pins for interfacing to

buttons or other digital devices. To monitor the battery

voltage in portable systems, the WM9711L has two

uncommitted comparator inputs.

• 2 comparator inputs for battery monitoring

• 1.8V to 3.6V supplies

• 7x7mm QFN or 48-pin TQFP package options

All device functions are accessed and controlled through a

single AC-Link interface compliant with the AC’97 standard.

Additionally, the WM9711L can generate interrupts to

indicate low battery, dead battery, thermal cut-out and GPIO

conditions.

APPLICATIONS

• Personal Digital Assistants (PDA)

• Smartphones

• Handheld and Tablet Computers

The WM9711L operates at supply voltages from 1.8 to 3.6

Volts. Each section of the chip can be powered down under

software control to save power. The device is available in a

small leadless 7x7mm QFN package, ideal for use in hand-

held portable systems, or in the industry standard 48-pin

TQFP package.
