Analog DevicesEVAL-CN0336-PMDZDevelopment Kits and Tools

Reference Design: 12-Bit, 300 kSPS, Single-Supply, Fully Isolated, Data Acquisition System for 4-20 mA Inputs

The EVAL-CN0336-PMDZ is a Pmod compatible evaluation board. It 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.
