    The EVAL-CN0337-PMDZ evaluation board circuit is a completely isolated 12-bit, 300 kSPS 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 3.3 V 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.

    The EVAL-CN0337-PMDZ circuit board uses the SDP-PMD-IB1Z, and the EVAL-SDP-CB1Z system demonstration platform (SDP) evaluation board. The SDP- PMD-IB1Z interposer board and the EVAL-SDP-CB1Z SDP board have 120-pin mating connectors. The interposer board and the EVAL-CN0337-PMDZ board have 12-pin Pmod matching connectors, allowing quick setup and evaluation of the circuit’s performance. The EVAL-CN0337-PMDZ board contains the circuit to be evaluated and the SDP evaluation board is used with the CN0337 evaluation software to capture the data from the EVALCN0337-PMDZ circuit board.

    Key Applications: Programmable Logic Controllers/ Distributed Control Systems, Temperature Controllers
