Automotive SENT Interface-Based Thermocouple Temperature Sensor with Cold Junction Compensation Using the ADuC7060/ADuC7061 Precision Analog Microcontroller

Application circuit uses the ADuC7060 or the ADuC7061 precision analog microcontroller in an accurate thermocouple temperature monitoring application. The ADuC7060/ADuC7061 integrate dual 24-bit sigma-delta analog-to-digital converters (ADCs), dual programmable current sources, a 14-bit digital-to-analog converter (DAC), and a 1.2V internal reference, as well as an ARM7 core, 32 kB flash, 4 kB SRAM, and various digital peripherals such as UART, timers, serial peripheral interface (SPI), and I2C interfaces
