Texas Instruments LM5166 / DAC8775 | Demoboard TIPD215
Less Than 1-W, Quad-Channel, Analog Output Module with Adaptive Power Management Reference Design
Overview
| Topology | Buck Converter |
| Input voltage | 12.5-40 V |
| Output 1 | 12 V / 0.5 A |
| IC revision | E1 |
Description
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.
Features
<1-W of Total Power Dissipation driving all four-channels at 20-mA<0.1 %FSR of Total Unadjusted Error in either Voltage or Current mode8-µA of Peak-to-Peak Current Output Ripple200-µV of Peak-to-Peak Voltage Output RippleAdaptive Power Management for Current Outputs
Typical applications
- Factory Automation & Control, Building Automation, Motor Drives
