AK4531A
Audio CODEC with 13ch Mixer & 18bit DAC
General Description
The AK4531A is a two channel 16bit AUDIO Hi-Fi CODEC (ADC and DAC) with a sampling rate of 4kHz to
50kHz and includes a 2 channel 18bit DAC designed to work together with an extra sound source. Each
converter can also operate by independent sampling rates. Its internal recording and playback mixer has 5
channel stereo and 3 channel mono with L/R, R/L, L/L and R/R switching. The AK4531A also has an
internal 30dB microphone amplifier. Its master clock is 256 times of fs and an internal PLL can also
automatically generates 256fs for master clock from fs. The sampling ADC has an enhanced dual bit delta
sigma modulator. Both the 16bit and 18bit DAC have low outband noise and high jitter tolerance due to a
switched capacitor filter(SCF) and a continuous time filter(CTF). The AK4531A corresponds to a 3.3V digital
interface, performing with a low power dissipation of 315mW. The package is a low profile 44pin LQFP.
