GENERAL DESCRIPTION

The AK5385B is a 24bit, 192kHz sampling 2ch A/D converter for high-end audio system. The modulator in

the AK5385B uses the Enhanced Dual Bit architecture and the AK5385B realizes high accuracy and low

cost. The AK5385B performs 114dB dynamic range, so the device is suitable for AV-amp, AV recorder

and musical instruments. The AK5385B is available in 28pin VSOP and SOP package, utilizing less board

space.
