WM9714L is a highly integrated input/output device designed for mobile computing and communications.

The WM8802 is a digital audio interface transceiver conforming to IEC 60958/61937 and EIAJ CP-1201. The device supports data sampling input rates of up to 192 kHz. Data input to the serial digital audio data input pin can also be modulated. The WM8802 features up to 6 data inputs and 1 data output. Data can be demodulated using the on-board PLL or with the use of an external clock source. The WM8802 is controlled via a 4-wire CCB compatible control interface. This interface provides access to the channel status bits. The WM8802 also provides a number of flag outputs including PCM data valid, de-emphasis, lock and IEC 61937, DTS-CD/LD detection. The device is available in a small 48-pin SQFP package.

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 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. 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. 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 handheld portable systems.

WM8746 is a high performance 6-channel digital audio decoder produced by Wolfson company, which supports 16-32 bit data input and 192 kHz sampling rate, and can be used in applications such as DVD, home theater systems and digital TV.

This document is about the production data of WM8738 24 Bit Stereo ADC, which is a high performance stereo audio ADC designed for consumer applications. It has 90 dB SNR ('A' weighted @ 48kHz) audio performance, supports 3.0-5.5V analog power operation and 3.0-3.6V digital power operation. The device supports 32kHz-96kHz ADC sampling frequency and 14-pin SOIC package.

The WM8722 is a high performance stereo DAC designed for audio applications such as digital TV and set top boxes. The WM8722 has two stereo analogue outputs, one at line level and one that includes a digitally controllable mute and attenuator function. An on-board tone generator can be routed through the line or variable outputs. WM8722 supports data input word lengths from 16-24 bits and sampling rates up to 96kHz.

The WM8726 is a high performance stereo DAC designed for audio applications such as DVD, home theatre systems, and digital TV. It supports data input word lengths from 16 to 24-bits and sampling rates up to 192kHz. The WM8726 consists of a serial interface port, digital interpolation filters, multi-bit sigma delta modulators and stereo DAC in a 14-pin SOIC package. The WM8726 has a hardware control interface for selection of audio data interface format, mute and de-emphasis. The WM8726 supports I2S, right Justified or DSP interfaces. The WM8726 is an ideal device to interface to AC-3, DTS, and MPEG audio decoders for surround sound applications, or for use in DVD players, including supporting the implementation of 2 channels at 192kHz for high-end DVD-Audio applications.

WM5620L and WM5620 are quad 8-bit digital to analogue converters (DAC) controlled via a serial interface. Each DAC's output voltage range is programmable for either x1 or x2 its reference input voltage, allowing near rail to rail operation for the x2 output range. Separate high impedance buffered voltage reference inputs are provided for each DAC. WM5620L operates on a single supply voltage of 3 V while WM5620 operates on 5 V. WM5620/L interfaces to all popular microcontrollers and microprocessors via a three wire serial interface with CMOS compatible, schmitt trigger, digital inputs. An 11 bit command word comprises 2 DAC select bits, an output range selection bit and 8-bits of data. Individual or all DAC outputs are changed using WM5620/L's double buffered DAC registers and the separate LOAD and LDAC inputs. DAC outputs are updated simultaneously by writing a complete set of new values and then pulsing the LDAC input. The DAC outputs are optimised for single supply operation and driving ground referenced loads. An internal power-on-reset function sets the DAC's input codes to zero at power up. Ideal in space critical applications WM5620/L is available in small outline and DIP packages for commercial (0oC to 70oC) and industrial (-40oC to 85oC) temperature ranges.

The WM2629 is an octal, 8-bit, resistor string digital-to-analogue converter with power down capability.
