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 AKMâs Enhanced Dual Bit architecture, enabling the AK5388 realizes to
realize high accuracy and low cost. The AK5388 achieves 120dB dynamic range and â105dB THD+N,
and an optional mono mode extends dynamic range to 121dB. The AK5388âs 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.
