Description

ZDS A / D converter AK9232NK / AK9233NK / AK9234NK integrates 2 channel circuits in a small 4 mm x 4 mm package enabling simultaneous sampling and saving board space. 
 The AK9232NK realizes 18-bit resolution while supporting the sampling rate up to 1.1 MHz. 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.
