High Performance Low-Latency Quad ADC

The AK5388 is a 24-bit, 216kHz sampling rate 4-channel A/D converter for high-end audio systems. The AK5388 achieves

120dB dynamic range and -110dB THD+N, and an optional dual-mono mode extends dynamic range to 123dB for stereo

operation. The AK5388’s digital filter features a modified FIR architecture that minimizes group delay while maintaining

excellent linear phase response. The modulator in the AK5388 uses AKM’s Enhanced Dual Bit architecture, enabling the

AK5388 to realize high accuracy and low cost. The device is ideal for professional audio applications including digital

recording, sound reinforcement, effects processing, sound cards, and high-end A/V receivers. The low-latency feature is

ideal for live sound applications. The AK5388 is available in a 44-pin LQFP package.

 Wide dynamic range

 Low distortion (THD+N)

 Low-latency digital filter

 TDM interface

 Master and slave mode

 Power supply

 44-pin LQFP package

VALUE PROPOSITION

The AK5388 is a revolutionary pro-audio ADC. It is the only 4-channel ADC that includes a high-performance

stereo mode (dual-mono mode), as well as a low-latency FIR digital filter. The choice between 120dB quad mode

and 123dB dual-mono mode provides flexibility for the designer. The AK5388 is a major upgrade from competing

4-channel parts, and it provides a superior cost:performance ratio.

Audio Performance

The AK5388 provides 120dB dynamic range in its nominal 4-channel mode. In mono mode, where the input signal

is applied to both left and right channels, dynamic range is boosted to 123dB. Since the AK5388 is a 4-channel

ADC, the mono mode provides two channels. In either mode, THD+N performance is -110dB, which is a -10dB

improvement over the quad AK5384 from AKM, and a -5dB improvement over the quad PCM4204 from TI.

Low Latency

This has become an issue for applications, and it can make a difference in live sound and musical instrument

applications. Low-latency solutions have employed short-delay IIR filters, but that filter architecture is not phase-

linear - certain frequencies are delayed by the filter, called phase distortion. The AK5388 uses a modified FIR

architecture, which provides a very short delay of 12.6/fs for any sampling frequency. The AK5388 digital filter

oversamples at 64-times for all sampling frequencies, so latency is consistent for any sampling frequency.
