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
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.

... The AK5352 has a Digital High Pass Filter(HPF) for DC-offset cancel. When HPFE pin goes "H", HPF is enabled. The cut-off frequency of the HPF is 1Hz(@fs=48kHz). It also scales with the sampling frequency(fs). The HPF can be disabled by bringing HPFE pin "L". In this case, the AK5352 has the DC-offset of a few mV. 0155-E-00 PD " ...
