The MAX6603 from Maxim Integrated Products is a small analog conditioner for interfacing resistive temperature devices (RTDs) to microcontrollers. It amplifies platinum RTD signals for ADC conversion, and provides up to ±5kV ESD protection. Targeted at next generation automotive engine-control systems that use exhaust temperature monitoring for EURO-IV emissions compliance, the MAX6603 replaces expensive discrete solutions, reduces board space and protects sensitive microcontroller inputs.
External RTD faults and system diagnostic status are indicated by a simple digital interface pin. The conditioner has low RD excitation current, which minimizes self-heating errors, does not require calibration, and simplifies system design.
