The CS42432 CODEC provides four multi-bit analog-to-digital and six multi-bit digital-to-analog delta-sigma converters. The CODEC is capable of operation with ei-ther differential or single-ended inputs and outputs, in a 52-pin MQFP package.Four fully differential, or single-ended, inputs are avail-able on stereo ADC1 and ADC2. Digital volume control is provided for each ADC channel, with selectable over- flow detection.All six DAC channels provide digital volume control and can operate with dif

The UAC 357xB is a new member of Micro-nas' USB audio IC family. It contains a high-performance stereo audio ADC/DAC and digital interfaces for audio or control data. The audio ADC with direct dual microphone and pseudo-differential stereo line input makes the UAC 357xB the ideal solution for all kinds of USB audio applications. This includes the replacement of analog sound cards in PCs. Integrated headphone ampli-fiers allow direct capless headphone con- nection. Therefore, the IC can be em

The WM8983 is a low power, high quality stereo CODEC designed for portable multimedia applications. Highly flexible analogue mixing functions enable new application features, combining hi-fi quality audio with voice communication.

DESCRIPTION The SSM2602 is a low power, high quality stereo audio codec for portable digital audio applications with one set of stereo programmable gain amplifier (PGA) line inputs and one monaural microphone input. It features two 24-bit analog-to-digital converter (ADC) channels and two 24-bit digital-to-analog (DAC) converter channels. The SSM2602 can operate as a master or a slave. It supports various master clock frequencies, including 12 MHz or 24 MHz for USB devices; standard 256 fS or 38

AK2305 is a dual PCM CODEC-Filter most suitable for ISDN Terminal Adapter. A-law/u-law is selected by the internal register. In addition to CODEC, this device has dual DTMF receiver and External Tone Input pin.

The WM8974 is a low power, high quality mono CODEC designed for portable applications such as Digital Still Camera or Digital Voice Recorder.

The UCB1400 is a stereo audio codec equipped with touch screen and power management interfaces. It integrates an AC '97 Rev. 2.1 interface for communication to an AC link host controller such as the Intel Xscale™ processor. The stereo audio codec inputs connect directly to a microphone or line level sources such as a CD player. The stereo audio codec outputs at line level and can drive a headphone directly. The touch screen interface connects directly to a 4-wire resistive touch screen
