AK4526A

ASAHI KASEI [AK4526A] www.DataSheet4U.com AK4526A High Performance Multi-channel Audio CODEC GENERAL DESCRIPTION The AK4526A is a single chip CODEC that includes two channels of ADC and six channels of DAC. The ADC outputs 20bit data and the DAC accepts up to 24bit input data. The ADC has an enhanced dual bit architecture with wide dynamic range. The DAC achieves low outband noise and high jitter tolerance by use of SCF(switched capacitor filter) techniques. An auxiliary digital audio input interface maybe used instead of the ADC for passing audio data to the primary audio output port. Control may be set directly by pins or programmed through a separate serial interface. The AK4526A has a dynamic range of 100dB and is well suited for digital surround for home theater and car audio. An AC-3 system can be built with a IEC958(SPDIF) receiver such as the AK4110. The AK4526A is available in a small 44pin LQFP package which will reduce system space. *AC-3 is a trademark of Dolby Laboratories.
