MAX6603
Overview
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 integrated analogto-digital converters (ADCs).

- Low RTD Excitation Current Minimizes SelfHeating Errors
- Small, 10-Pin TDFN Package
- Fully Ratiometric Operation
- No Calibration Required for Standard RTDs
- RTD Diagnostic Check
- High Accuracy: ±6°C (max) from +400°C to +600°C Features
- Amplifies Pt R
