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. (AKM is the Asahi Kasei Microdevices Corporation)

Key Features

  • Zero Latency Delta Sigm type modulation ADC.
  • High precision conversion, high speed response

Applications

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