AK5352

96kHz Sampling ∆Σ 20bit ADC

GENERAL DESCRIPTION

The AK5352 is a 20-bit, 96kHz sampling rate for DAT and DVD, 64x oversampling rate(64fs), 2-channel A/D

converter for stereo digital systems. The ∆Σ modulator in the AK5352 uses the new developed Enhanced Dual

bit architecture. This new architecture achieves the wider dynamic range, while keeping much the same

superior distortion characteristics as the conventional Single bit way.

The AK5352 is available in a small 24pin VSOP package which will reduce your system space.
