AK5366VR
24-Bit 48kHz ∆Σ ADC with Selector/PGA/ALC
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.
