In Data Acquisition, Digital to analog conversion plays a crucial role. A Vast number of devices and equipment types are out there which can be controlled by voltage variation from 0V to 10V. Aptinex DA4C010BI is a perfect solution for this. This module is using I2C as its communication protocol and therefore major microcontrollers or other hardware platforms can use this without much of hustle-bustle. Unlike its single channel predecessor DA1C010BI, DA4C010BI is having the capability of controlling 4 Channels at once.
