Output drivers for industrial applications
25 June 2008
Power Electronics / Power Management
Analog Devices has introduced two analog output drivers designed to improve the efficiency and reliability of process control applications, including those operating with high compliance voltages and temperatures.
Using technological advancements enabled by the company’s iCMOS industrial process technology, the AD5750 and AD5751 output drivers provide an accuracy level of 0,1% TUE (total unadjusted error) under all operating conditions. They condition the output of a low-voltage, single-supply DAC (digital-to-analog converter) to provide high performance voltage- and current-output-drive capability.
Designed to meet the growing demand for highly configurable industrial automation controllers, the new output drivers offer extensive diagnostic functionality such as fault detection and enhanced sensing capabilities to ease system startup and troubleshooting. Integrating user-programmable current- and voltage-output capabilities, the drivers are suited for programmable logic controllers, distributed control and high-voltage analog I/O systems.
The AD5750, which operates from dual ±12 V to ±24 V supplies, offers four output voltage ranges (0–5 V, 0–10 V, ±5 V, ±10 V) and five output current ranges (4–20 mA, 0–20 mA, 0–24 mA, ±20 mA, ±24 mA), with 20% over-range capability.
The AD5751 operates from a single 10,8V to 60 V supply, facilitating reliable factory communications over long cables. It offers three output voltage ranges (0–5 V, 0–10 V, 0–40 V) and three output current ranges (4–20 mA, 0–20 mA, 0–24 mA), with 20% over-range capability.
Both devices incorporate a 30 MHz serial peripheral interface (SPI) and power-on reset circuitry and are fully specified over a –40°C to +105°C temperature range. They integrate packet-error checking (PEC) features that verify the interface data has been correctly received in the presence of noise, which is useful in industrial environments where data communication corruption can occur.
