Description du kit de développement
EVAL-CN0287-SDPZ is Isolated 4-Channel, Temperature Measurement Circuit Optimized Evaluation Board. Itsupports all types of thermocouples with cold junction compensation and any type ofRTD (resistance temperature detector) with resistances up to 4 kΩ for 2-, 3-, or 4-wire connection configurations. TheRTD excitation current are is programmable for optimum noise and linearity performance.
RTD measurements achieve 0.1°C accuracy (typical), and Type-K thermocouple measurements achieve 0.05°C typical accuracy because of the 16-bit ADT7310 digital temperature sensor used for cold-junction compensation. The circuit uses a four-channel AD7193 24-bit sigma-delta ADC with on-chip PGA for high accuracy and low noise.Input transient and overvoltage protection are provided by low leakage transient voltage supressors (TVS) and Schottky diodes. The SPI-compatible digital inputs and outputs are isolated (2500 V rms), and the circuit is operated on a fully isolated power supply.
