AK9243 - AFE

Download the AK9243 datasheet PDF. This datasheet also covers the AK9242 variant, as both devices belong to the same afe family and are provided as variant models within a single manufacturer datasheet.

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.

[AK9242/43] = Preliminary = 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.
