Description

ZDS A/D converter AK9232NK/AK9233NK/AK9234NK integrates 2-channel circuits in a small 4mm x 4mm package enabling simultaneous sampling and saving board space. 
 The AK9232NK realizes 18-bit resolution while supporting the sampling rate up to 1.1MHz. In addition, it has polar coordinates output function (angle calculation algorithm); a small high accuracy encoder can easily be designed.
(*) ZDS: Zero Latency Delta Sigma
A ZDS 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. It contributes to improving the speed and the accuracy of negative feedback circuits. It has long acquisition time comparing with an SAR A/D converter, reducing input buffer load of the IC. Small and high accurate motor systems can be designed with a ZDS A/D converter.

Applications

  •                                 Contributes to high speed and accuracy in the negative feedback system
