EVAL-CN0337-PMDZ

EVAL-CN0337-PMDZ is a CN0337 circuit evaluation board. It is a completely isolated 12-bit, 300kSPS RTD temperature measuring system that uses only three active devices. The system processes the output of a Pt100 RTD and includes an innovative circuit for lead-wire compensation using a standard 3-wire connection. The circuit operates on a single 3.3V supply. The total error after room temperature calibration is less than ±0.24% FSR for a ±10°C change in temperature, making it ideal for a wide variety of industrial temperature measurements. The small footprint of the circuit makes this combination an industry-leading solution for temperature measurements where accuracy, cost, and size play a critical role. Both data and power are isolated, thereby making the circuit robust to high voltages and also ground-loop interference often encountered in harsh industrial environments.
