The DAC8760IRHAR is a single-channel, 16-bit, fully integrated, loop-powered, voltage and current output digital-to-analog converter (DAC) from Texas Instruments, housed in a compact 40-pin VQFN (RHA) package. It is designed for direct interface with industrial process control systems, offering a wide 24-V to 65-V supply range and comprehensive on-chip diagnostics, making it a robust solution for generating 4-mA to 20-mA or 0-V to 5-V/10-V analog control signals.
Key Features and Highlights:
● Loop-Powered Operation & Wide Supply Range: Operates from a single 24-V to 65-V loop supply, eliminating the need for an additional isolated power supply and simplifying system design in harsh industrial environments.
● Fully Integrated Voltage/Current Output: Generates both voltage (0 V to 5 V, 0 V to 10 V, ±5 V, ±10 V) and current (0 mA to 20 mA, 4 mA to 20 mA) outputs from a single device, providing design flexibility for various field transmitter and actuator interfaces.
● High Accuracy and Resolution: Provides 16-bit monotonic performance with low integral nonlinearity (INL) and excellent total unadjusted error (TUE), ensuring precise control signal generation for sensitive industrial processes.
● Comprehensive Integrated Diagnostics: Features on-chip diagnostics for open/short circuit detection, thermal overload, and compliance voltage monitoring, enabling predictive maintenance and enhancing system reliability.
● Industrial Communication Interface: Includes a flexible SPI-compatible serial interface with daisy-chain capability, allowing easy connection to microcontrollers and digital isolators in distributed control systems.
Frequently Asked Questions (FAQ)
Q: How does the open-circuit detection diagnostic work?
A: The DAC8760 monitors the output voltage when configured in current output mode. If the output attempts to drive current into a load that is disconnected (open circuit), the output compliance voltage will rise to its maximum. The internal diagnostic circuit detects this condition and can flag a fault via the SPI interface.
