AK5388
120dB，192kHz，24位4声道ADC
120dB 192kHz 24-Bit 4ch ADC
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 device to realize high accuracy and low cost. The AK5388 achieves 120dB dynamic range and -110dB THD+n, and an optional mono mode allows dynamic range to extend to 123dB. The AK5388's digital filter features an advanced FIR architecture that minimizes group delay while maintaining excellent linear phase response, enabling the device to meet the demand of professional audio applications including recording, sound reinforcement, effect processing, sound cards, and high-end A/V receivers. The AK5388 is available in 44pin LQFP package. |
