The EVAL-CN0287-SDPZ is a circuit evaluation board that is completely isolated 4 channel temperature measurement circuit optimized for performance, input flexibility, robustness and low cost. This circuit evaluation board uses AD7193 24bit sigma delta ADC, ADT7310 temperature sensor, AD8603 op amp, ADR3440 4.096V voltage reference, ADG738 three wires serially controlled, matrix switch, ADG702 SPST switch, AD5201 33 position digital potentiometer, ADuM1280 isolator and ADuM5401 2.5KV Isolators with Integrated DC to DC converter. This circuit evaluation board supports all types of thermocouples with cold junction compensation and any type of RTD (resistance temperature detector) with resistances up to 4Kohm for 2, 3, or 4 wire connection configurations. The RTD excitation current are is programmable for optimum noise and linearity performance. Input transient and overvoltage protection are provided by low leakage transient voltage suppressors (TVS) and schottky diodes.
