ADC (AD7680) component

16-bit external ADC connected to the microcontroller using SPI.

Component Source Code

Please click here to download the component source project: FC_Comp_Source_ExternalADC_AD7680.fcfx

Detailed description

Overview

The AD7680 is a 2.5V to 5.5V SPI compatible, successive approximation analogue to digital converter (ADC).

The reference for the AD7680 is taken internally from VDD


Pin reference from the datasheet:

AD7680 Pin Reference.png

Examples

This example reads the voltage on the AD7680 Vin and converts the ADC results into a voltage. For the result to be correct, you must change the Voltage variable to match the supply voltage.
