MAX6603 Datasheet | Maxim Integrated

19-3975; Rev 0; 4/06 Dual-Channel, Platinum RTD-to-Voltage Signal Conditioner General Description 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). External precision resistors and calibration processes are not needed. The MAX6603 provides the necessary signal-conditioning .. functions, including ratiometric excitation...
