In summary, a discrete DO module design will be a challenge to keep heat and power dissipation low while adding more channels and maintaining either the same size or reducing size. With Analog Devices' MAX14900E, a 16-channel DO module design can be realized in a fairly small form factor with many benefits. The MAX14900E lowers heat and power dissipation with 20% lower RDSON and enables flexible designs with serial or parallel configurations and high-side or push-pull modes for the output. Extensive diagnostics on individual channels and global parameters and protection features increase equipment up time, while all doing this in a compact size.
