GENERAL DESCRIPTION
AK5366 is a high-performance 24-bit, 48kHz sampling ADC for consumer audio and digital recording
applications. Thanks to AKM's Enhanced Dual-Bit modulator architecture, this analog-to-digital converter
has an impressive dynamic range of 103dB with a high level of integration. The AK5366 has a 5-channel
stereo input selector, an input Programmable Gain Amplifier with an ALC function. All this integration with
high-performance makes the AK5366 well suited for CD and DVD recording systems.
