GENERAL DESCRIPTION

The AK5388 is a 24bit, 216kHz sampling 4-channel A/D converter for high-end audio systems. The modulator in the AK5388 uses AKM’s Enhanced Dual Bit architecture, enabling the AK5388 to realize high accuracy and low cost. The AK5388 achieves 120dB dynamic range and 110dB S/N+D), and an optional mono mode extends dynamic range to 123dB. The AK5388’s digital filter features a modified FIR architecture that minimizes group delay while maintaining excellent linear phase response. So the device is suitable for professional audio applications including recording, sound reinforcement, effects processing, sound cards, and high-end A/V receivers.The AK5388 is available in 44pin LQFP package.
