GENERAL DESCRIPTION

AK5366VR 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 AK5366VR has a 5-channel stereo input selector, an input Programmable Gain Amplifier with an ALC function. All this integration with high-performance makes the AK5366VR well suited for CD and DVD recording systems.
