AK8441VQ

Analog To Digital Converters (ADC) Overview

The AK8441VQ is a 6-channel analog front-end integrated circuit designed for linear CCD sensors, manufactured by Asahi Kasei Microdevices. It integrates Correlated Double Sampling (CDS) circuits and Programmable Gain Amplifiers (PGAs) to process sensor signals. The device supports a maximum sampling speed of 35 MSPS per channel in CDS mode. It features adjustable gain ranges via 8-bit PGAs and offset compensation through independent DACs. The component operates on a 3.3V supply and utilizes a 4-wire serial interface for configuration. It is housed in a 64-pin LQFP package with a 0.5 mm pitch.
