Description

The AK9255ANK is 16-bit 0.5 MSPS ZDS-NS A / D converter(※)
 This product is ZDS A / D converters with noise suppression function and capable of improving the system accuracy.
 The AK9255ANK is available in a small package, saving space on the printing board.
 In addition, 14-bit option, AK9256ANK and different output interface options, the AK9255NK and the AK9256NK, are also available.
(※) ZDS-NS | Zero latency Delta Sigma with Noise Suppression. , 
A ZDS-NS A / D converter realizes ultrafast response of SAR while maintaining high accuracy conversion like a delta-sigma converter, based on AKM’s accumulated experience and know-how in analog-digital LSI technology. A ZDS-NS A / D converter has smaller input capacitance than SARs, reducing the buffer load of the input stage of the IC. Furthermore, the oversampling process is executed inside of the IC, and the averaging process is carried out with a built-in digital filter. Therefore, analog input signal noise can be suppressed, contributing to improving noise characteristics of the system. It also contributes to high-speed processing of a system that needs a noise averaging.
