AK9243 Datasheet Afe

Manufacturer: AKM (Asahi Kasei Microdevices)

Overview: [AK9242/43] = Preliminary = AK9242/43 AFE with Dual 16/14-Bit 1.

This datasheet includes multiple variants, all published together in a single manufacturer document.

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 microputer.
