EVAL-CN0394-ARDZ

Reference Design: Flexible, Low Power, 4-Channel Thermocouple System with Arduino-Compatible Analog Interface

The EVAL-CN0394-ARDZ is a flexible, integrated, 4-channel thermocouple measurement system based on the Arduino compatible ADuCM360, a low power, precision analog microcontroller. The ADuCM360 has an Arm Cortex™-M3 processor core, a number of peripherals, and also precision analog functions including a dual, 24-bit, Σ-Δ ADC; multiplexer; programmable gain amplifier (PGA); and voltage reference.
