AK5388

120dB 24-bit 192kHz 4-Channel ADC

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 realizes to

realize high accuracy and low cost. The AK5388 achieves 120dB dynamic range and –105dB THD+N,

and an optional mono mode extends dynamic range to 121dB. 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.
