MAXREFDES1155: Dual Channel RTD/TC Measurement System Based on MAX11410


 Download Full Reference Design



MAXREFDES1155 is a configurable two-channel resistance temperature detector (RTD)/thermocouple (TC) measurement system. Each channel can be configured for either RTD or TC input. The RTD can be either a PT100 or a PT1000 connected in a 2-wire, 3-wire, or 4-wire configuration. The MAXREFDES1155 can support all types of thermocouples, using either an on-board temperature sensor or an RTD for cold-junction compensation.
