About This Webinar	More Channels in Less Space: New Trends in Highly Integrated DACs How a Highly Integrated Quad Channel Analog output module with Adaptive power management Solves the space demand problem in factory automation Trends in the factory automation space demand that designers fit more channels in a smaller space. This means that systems are getting more dense, designers have to manage the system thermals better due to the need for high reliability, and efficiency is extremely important. This TI design addresses some of these key challenges by using a highly integrated quad channel 4-20mA and voltage output DAC with integrated adaptive power management. In addition, we will also discuss a reference design used to pass IEC61000-4 suite of tests. This quad-channel, analog output module delivers voltage and current outputs using the highly integrated DAC8775 digital-to-analog converter (DAC). Integrated adaptive power management, along with the LM5166 buck converter, reduces the total power dissipation of the reference design to less than 1 W, even when driving all four channels at 20 mA simultaneously.

Reference Design: Less Than 1-W, Quad-Channel, Analog Output Module with Adaptive Power Management Reference Design

This quad-channel, analog output module delivers voltage and current outputs using the highly integrated DAC8775 digital-to-analog converter (DAC). Integrated adaptive power management, along with the LM5166 buck converter, reduces the total power dissipation of the reference design to less than 1 W, even when driving all four channels at 20 mA simultaneously.

Just watched the recording. Great presentation. Volume level was a bit low.

On a side note, please consider adding point system for viewing webinars. The content of the webinars is very rewarding but if members received some points for watching a webinar, this could increase interest. Community members are awarded points for a variety of actions. It would be nice if members received a few points for attending and viewing the recorded webinars. Unfortunately I have been unable to view a live webinar yet. I will be making an effort to attend future webinar events.

Webinar recording is now available

Ok, now you have me interested enough to attend the Webinar.

Hi Lex,

The DAC8775 is targeted towards three primary applications (at least using TI terminology ); factory automation & control, motor control, and building automation. Most of these systems use what's historically ubiquitously been dubbed "4-20mA loops", despite not all of them being designed in a 2-wire, or loop powered architecture (there also exist 3-wire and 4-wire systems).

The main goal was to help increase density of these modules by integrating more channels and reducing on-board power / heat dissipation. We'll talk more about this in the Webinar.

For the hobbyist - depending on the infrastructure in your home - there could be some opportunities to use the device to communicate with your HVAC system primarily. The other benefit of having the communication basis in the current domain, as opposed to voltage domain, is you could maybe put a few of these in a "module" format in your attic or something and be able to run actuators or motors elsewhere in your house, maybe raise / lower blinds, open / close doors, etc. without worrying about catching your insulation on fire

Thank you for the prompt response, Kevin. Yes, we've had the ability to read, write and manipulate data over the USB with a Human Interface Device library since kernel 2.6.x, since it's the generic HID…
