Audio Codec With Touch Screen Controller

The AK4533 is Audio CODEC with Touch Screen controller. The AK4533 incorporates several functions into one-chip; the position detection of the Touch Screen the measurement of battery voltage, the record of the voice, and the playback of Audio data. The AK4533 has monaural A/D converter with AGC, and stereo D/A Converter with digital Attenuator As codec CAN operate from 8kHz to 44.1kHz, the AK4533 CAN playback the sound like MP3 with high quality. On-chip digital Attenuator with 1.5dB step CAN control DAC volume without the increase of CPU load. As AGC with 0.5dB step automatically controls voice input level to the appropriate level, the voice CAN be recorded clearly. As the AK4533 also has on-chip 20dB fixed gain preamplifier in addition to AGC, no other external preamplifier for Microphone is required. The AK4533 controls the voltages which are supplied to two pairs of electrode of Touch Screen As the AK4533 also has 12bit/100kHz sampling SAR type A/D converter it is possible to detect the pressed location by two A/D conversions. 12 bit digital code is output through serial Interface The AK4533 also has 2 Analog channels as the input of Touch Screen A/D converter. The main purpose is for the measurement of the battery voltage. By AKM Semiconductor, Inc.
