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.
