TIDA-010988
Eight-channel V and I combined analog input module with single supply reference design
TIDA-010988
概覽
The TIDA-010988 is an eight-channel analog input module with 2-terminal inputs for industrial automation applications. Each channel supports software-selectable voltage range of 0V to 10V and ±10V, as well as current range of 4mA to 20mA, ±20mA. The design implements a high-density isolated analog input module powered from either a single 24V field supply or 5V USB. By using the ADS125H18 chip-select forwarding feature, the design implements a shared SPI architecture that reduces the required digital isolation channel count. The system is designed to achieve over temperature system absolute accuracy error better than 0.1% for voltage input and 0.2% for current input.
特點
- Eight identical 2-terminal analog input channels
- Per-channel support for voltage (0V to 10V, ±10V) and current (4mA to 20mA, ±20mA) input
- Photo‑MOS based voltage and current switching with open‑wire detection on each channel
- Integrated PTC, TVS, and Zener diodes input protection for robust industrial interfaces
- Single 24V supply or 5V USB supply for evaluation
- System absolute accuracy error:
- Over temperature (–40°C to 125°C), Voltage: <0.1%, Current: <0.2%
- Room temperature (25°C), Voltage: <0.05%, Current: <0.15%
