MAX6603 Platinum RTD-to-Voltage Signal Conditioner

The MAX6603 dual-channel, platinum RTD-to-voltage signal conditioner excites and amplifies the signal from two external 200 Ω platinum-resistive temperature devices (Pt RTD) to achieve high-voltage, level-filtered signals for temperature measurements. The MAX6603 provides a direct ratiometric output voltage to simplify the interface to microcontrollers with .

Features

a ±6°C (max) accuracy over the +400°C to +600°C temperature range. The MAX6603 has overvoltage protection up to +16V on RTD inputs, and ±5kV electrostatic discharge (ESD) protection at RTD input pins for reliable operation where RTD temperature-sensing probes are used. The MAX6603 monitors the RTD for faults and asserts the respective DG output low for fault conditions. The analog voltage outputs can be readily connected to a variety of microcontrollers. The MAX6603 is available in a small, 10-pin TDFN-EP package and operates over the -40°C to +125°C automotive temperature range from a single .
