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. FEATURE 1. Resolution: 16bits 2. Recording Function: • 3-Input Selector (Internal MIC, External MIC, LINE) • Pre-Amp/EQ-Amp • HPF-Amp for wind-noise • Digital ALC (Auto Level Control) circuit • FADEIN / FADEOUT • Digital HPF for offset cancellation (fc=3.7Hz@fs=48kHz) 3. Playback Function • Digital De-emphasis Filter (tc = 50/15us, fs = 32kHz, 44.1kHz and 48kHz) • LINEOUT Buffer: +2dBV • Analog Volume - 0dB ∼ -50dB, Mute • Headphone-Amp - Output Level: -3.4dBV, THD+N = 1% • Speaker-Amp with a built-in Digital ALC circuit - BTL Output - Output Power: 80mW @ 8Ω • BEEP and Shutter Signal Inputs 4.
