Features, Applications

GENERAL DESCRIPTION The a 16bit stereo CODEC with a built-in Microphone-Amplifier, Headphone-Amplifier and Speaker-Amplifier. Input circuits include Microphone-Amplifier and ALC (Auto Level Control) circuit. And output circuits include Headphone-Amplifier and Speaker-Amplifier. Therefore the AK4534 suits a PDA. The package is 48pin LQFP and the package 52pin of QFN. A new system can be smaller board area than a current system is composed or 3 chips. FEATURES 1. Resolution 16bits 2. Recording Function 1ch Mono Input 1st MIC Amplifier 0dB 2nd Amplifier with ALC +27.5dB, 0.5dB Step, Mute ADC Performance : S/(N+D) : 70dB, DR, S/N 80dB 3. Playback Function Digital De-emphasis Filter 44.1kHz, 48kHz) Digital Volume -127dB, 0.5dB Step, Mute) Headphone-Amp - HP-AMP Performance : S/(N+D) : 70dB, S/N 88dB - Output Power 15mW@16 (HVDD=3.3V) (Required external 6.8 series resistor) Mono Speaker-Amp with ALC - SPK-AMP Performance : S/(N+D) : 50dB, S/N 85dB - BTL Output - Output Power 150mW@8 (HVDD=3.3V) Mono and Stereo Beep Input Mono Line Output 4.
