Getting started with the STEVAL-AKI002V1 evaluation board for the ADC1283
analog-to-digital converter
Introduction
The
STEVAL-AKI002V1
evaluation board allows evaluating the conversion performance of the
ADC1283
eight-channel analog-
to-digital converter, which is designed for 50 ksps to 200 ksps conversion.
The board can accept external signals to measure and evaluate the
ADC1283
conversion performance, based on its successive
approximation register (SAR) with an internal track-and-hold cell.
A reference voltage is also present on the board that can be connected to one of the channels through a jumper.
The board can be supplied in standalone mode. It can also be connected to a
NUCLEO-L476RG
development board hosting an
STM32 microcontroller, which enables further signal processing and PC communication.
To monitor the
STEVAL-AKI002V1
performance, when connected to the NUCLEO-L476RG, you can use the
STSW-AKI
GUI.
