AK9242/43
AFE with Dual 16/14-Bit 1.1MSPS ZDS A/D Converter
General Description
The AK9242/43 are Analog Front Ends with 16/14-bit 1.1MSPS ZDS* A/D converters. They integrate a
programmable gain amplifier (PGA) that is able to select the input current and the input voltage realizing
to control the input range. A polar coordinate calculation function is also integrated, and it reduces the
load of DSP or microcomputer. The AK9242/43 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.
