Микросхемы и комплектующие EVAL-CN0300-EB1Z

The EVAL-CN0300-EB1Z is a circuit evaluation board for 12bit, 4mA to 20mA loop powered thermocouple measurement system using ARM Cortex-M3. This circuit uses the ADuCM360 precision analog microcontroller in an accurate thermocouple temperature monitoring application and controls the 4mA to 20mA output current accordingly. The ADuCM360 integrates dual 24bit sigma delta analog to digital converters (ADCs), dual programmable current sources, a 12bit digital to analog converter (DAC), and a 1.2V internal reference, as well as an ARM Cortex-M3 core, 126KB flash, 8KB SRAM and various digital peripherals such as UART, timers, SPIs, and I2C interfaces. In the circuit, the ADuCM360 is connected to a type T thermocouple and a 100ohm platinum resistance temperature detector (RTD). The circuit provides a complete solution for thermocouple measurements with a minimum requirement for external components, and it is loop powered for loop voltages up to 28V.

• T type thermocouple measurement system, to loop powered 4mA to 20mA output
