Circuits from the Lab® reference designs from Analog Devices have been designed and built by Analog
Devices engineers. Standard engineering practices have been employed in the design and
construction of each circuit, and their function and performance have been tested and verified in a lab
environment at room temperature. However, you are solely responsible for testing the circuit and
determining its suitability and applicability for your use and application. Accordingly, in no event shall
Analog Devices be liable for direct, indirect, special, incidental, consequential or punitive damages due
to any cause whatsoever connected to the use of any Circuits from the Lab circuits. (Continued on last page)

CIRCUIT FUNCTION AND BENEFITS
The circuit shown in Figure 1 is a complete thermopile-based gas
sensor using the nondispersive infrared (NDIR) principle. This
circuit is optimized for CO
2
sensing, but can also accurately
measure the concentration of a large number of gases by using
thermopiles with different optical filters.
The printed circuit board (PCB) is designed in an Arduino
shield form factor and interfaces to the EVAL-ADICUP360
Arduino-compatible platform board. The signal conditioning is
implemented with the AD8629 and the ADA4528-1 low noise
amplifiers and the ADuCM360 precision analog microcontroller,
which contains programmable gain amplifiers, dual 24-bit Σ-Δ
analog-to-digital converters (ADCs), and an ARM Cortex-M3
processor.
