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.
FEATURES
1. 24bit Stereo ADC

• Digital HPF for offset cancellation (fc=1.0Hz@fs=48kHz)
• Digital Attenuator
• Soft Mute
• Single-end Inputs
• S/(N+D) : 94dB
• DR, S/N : 103dB
• Audio I/F Format : 24bit MSB justified, I
