WM9712L

AC’97 Audio and Touchpanel CODEC

DESCRIPTION

FEATURES

 AC’97 Rev 2.2 compatible stereo CODEC

- DAC SNR 94dB, THD –87dB

The WM9712L is a highly integrated input / output device

designed for mobile computing and communications. The

device can connect directly to a 4-wire or 5-wire touchpanel,

mono or stereo microphones, stereo headphones and a

mono speaker, reducing total component count in the

system. Additionally, phone input and output pins are

- 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)

provided

for

seamless

integration

with

wireless

communication devices.

The WM9712L also offers up to four auxiliary ADC inputs for

analogue measurements such as temperature or light, and

five GPIO pins for interfacing to buttons or other digital

devices. To monitor the battery voltage in portable systems,

the WM9712L has two uncommitted comparator inputs.

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

 Seamless interface to wireless chipset

 Resistive touchpanel interface

- Supports 4-wire and 5-wire panels

- 12-bit resolution, INL 2 LSBs (<0.5 pixels)

- X, Y and touch-pressure (Z) measurement

- Pen-down detection supported in Sleep Mode

 Up to 5 GPIO pins

All device functions are accessed and controlled through a

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

Additionally, the WM9712L can generate interrupts to

indicate pen down, pen up, availability of touchpanel data,

low battery, dead battery, and GPIO conditions.

 2 comparator inputs for battery monitoring

 Up to 4 auxiliary ADC inputs

 1.8V to 3.6V supplies

The WM9712L 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.

 7x7mm QFN

APPLICATIONS

 Personal Digital Assistants (PDA)

 Smartphones

 Handheld and Tablet Computers
