AD5420AREZ-REEL7

AD5420 is a low cost, precision, fully integrated 16bit converter offering a programmable current source output designed to meet the requirements of industrial process control applications. The flexible serial interface is SPI, MICROWIRE™, QSPI™, and DSP compatible and can be operated in 3-wire mode to minimize the digital isolation required in isolated applications. The device also includes a power-on reset function, ensuring that the device powers up in a known state, and an asynchronous CLEAR pin that sets the output to the low end of the selected current range. It is widely used in application such as process control, actuator control PLC, HART network connectivity etc.

• Current output range is 4mA to 20mA, 0mA to 20mA, or 0mA to 24mA
• Total unadjusted error (TUE) is 0.15% maximum
• Output drift is ±3ppm/°C typical
• Flexible serial digital interface, on-chip output fault detection
• On-chip reference is 10ppm/°C maximum
• Feedback/monitoring of output current, asynchronous clear function
• Power supply (AVDD) range is 10.8V to 40V
• Output loop compliance to AVDD is -2.5V
• Operating temperature range is −40°C to +85°C
• Package style is 24-lead TSSOP-EP
