GENERAL DESCRIPTION
AK4561 is a 16bit stereo CODEC with a built-in Microphone-Amp, Headphone-Amp. Input circuits include Microphone/LINE inputs selector, power supply for microphone, Pre-Amp, HPF-Amp, EQ-Amp and ALC (Automatic Level Control) circuit, and output circuits include LINEOUT buffer, Analog Volume and Headphone-Amp. As Multi-Power-Supply-System can be set a suitable power supply voltage in each block, the AK4561 is compatible with high performance and low power dissipation. The package is a 64pin TQFP, therefore, a new system can be a smaller board area than a current system is composed of 2 or 3 chips.
