    The EVAL-CN0336-PMDZ evaluation board circuit is a completely isolated 12-bit, 300 kSPS data acquisition system utilizing only three active devices. The system processes 4 mA to 20 mA input signals using a single 3.3 V supply. The total error after room temperature calibration is ±0.06% FSR over a ±10°C temperature change, making it ideal for a wide variety of industrial measurements.

    The small footprint of the circuit makes this combination an industry-leading solution for 4 mA to 20 mA data acquisition systems where the accuracy, speed, 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.

    This circuit uses the EVAL-CN0336-PMDZ circuit board, the SDP-PMD-IB1Z and the EVAL-SDP-CB1Z system demonstration platform (SDP) evaluation board. The interposer board SDP-PMD-IB1Z and the SDP board EVAL-SDP-CB1Z have 120-pin mating connectors. The interposer board and the EVAL-CN0336-PMDZ board have 12-pin Pmod matching connectors, allowing quick setup and evaluation of the circuit’s performance. The EVAL-CN0336-PMDZ board contains the circuit to be evaluated and the SDP evaluation board is used with the CN0336 evaluation software to capture the data from the EVAL-CN0336-PMDZ circuit board.
