GENERAL DESCRIPTION
AK4560A is a 16bit stereo CODEC with a built-in Microphone-Amp, Headphone-Amp and Speaker-Amp. Input
circuits include Microphone/LINE inputs selector, power supply for microphone, Pre-Amp, HPF-Amp, EQ-Amp
and ALC (Auto Level Control) circuit, and output circuits include LINEOUT buffer, Analog Volume,
Headphone-Amp and Speaker-Amp, therefore the AK4560A suits a portable application with a built-in LCD
and etc. As Multi-Power-Supply-System can be set a suitable power supply voltage in each block, the
AK4560A is compatible with high performance and low power dissipation. The package is a 64pin LQFP,
therefore, a new system can be a smaller board area than a current system is composed of 2 or 3 chips.
