General Description
The MAX6603 dual-channel, platinum RTD-to-voltage
signal conditioner excites and amplifies the signal from
two external 200
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.
The MAX6603 is available in a small, 10-pin TDFN-EP
package and operates over the -40°C to +125°C auto-
motive temperature range from a single +3V to +5.5V
power supply.
