Sub 1-W: 16-Channel: Isolated Digital Input Module Reference Design
Description
This reference design shows a compact implementation of 16 isolated digital input channels using TI's ISO121x devices. The design works without an isolated supply and supports up to 100-kHz input signals (200-kbit) per channel. All 16 channels consume less than 1-W input power combined: which enables a compact layout and results in minimum heat dissipation.
Features
- 16 digital input channels with up to ±60-V input voltage toleranceWorks with primary supply only: no isolated power supply neededParallel and serial output option±6-kV IEC 61000-4-2 ESD performanceDesigned to withstand ±2-kV surge and EFT burst tolerantLaunchPad™ header for quick and easy evaluation
