GENERAL DESCRIPTION

AK5365 is a high-performance 24-bit, 96kHz 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 AK5365 has a 5-channel

stereo input selector, an input Programmable Gain Amplifier with an ALC function. All this integration with

high-performance makes the AK5365 well suited for CD and DVD recording systems.
