AK9232

[AK9232/33/34] = Preliminary = AK9232/33/34 Dual 18/16/14-Bit 1.1MSPS ZDS A/D Converter General Description The AK9232/33/34 are 18/16/14-bit 1.1MSPS ZDS* A/D converters. A polar coordinate calculation function is also integrated, and it reduces the load of DSP or microcomputer. The AK9232/33/34 are housed in a space-saving 24-pin QFN package. * ZDS: Zero latency Delta Sigma A ZDS A/D converter realizes ultrafast response of SAR with 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 improve the speed and the accuracy of negative feedback system. A ZDS A/D converter can achieve small and high accurate motor systems.
