Description
- Application Circuit uses the ADuCM360 precision analog microcontroller in an accurate thermocouple temperature monitoring application and controls the 4 mA to 20 mA output current accordingly. The ADuCM360 integrates dual 24-bit sigma-delta analog-to-digital converters (ADCs), dual programmable current sources, 12-bit digital-to-analog converter (DAC) and a 1.2V internal reference, as well as an ARM Cortex-M3 core, 126 kB flash, 8 kB SRAM and various digital peripherals such as UART, timers, SPIs and I2C interfaces
