Dual-Channel, Platinum RTD-to-Voltage

Signal Conditioner

General Description

Features

The MAX6603 dual-channel, platinum RTD-to-voltage

signal conditioner excites and amplifies the signal from

two external 200Ω 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 integrated analog-

to-digital converters (ADCs). External precision resis-

tors and calibration processes are not needed. The

MAX6603 provides the necessary signal-conditioning

functions, including ratiometric excitation current,

amplification, buffered voltage outputs, diagnostic fault

detections, and input protection. The MAX6603 ampli-

fies signals from two RTDs operating over the -40°C to

+1000°C temperature range and provides the tempera-

ture information as two independent analog voltages.

The MAX6603 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 ana-

log voltage outputs can be readily connected to a vari-

ety of microcontrollers.
