Expose Temperatures Wirelessly with the Maxim Novato Reference Design from Mouser

by donpedro

Mouser Electronics, Inc. is now shipping the new MAXREFDES16 Novato Reference Design board from Maxim Integrated. This reference design provides a complete signal chain

solution for wirelessly transmitting remote temperature information.
The new maxim MAXREFDES16 Novato Reference Design board available from Mouser Electronics is a highly accurate 16-bit temperature transducer system that wirelessly transmits remote temperature information to a central control unit over a 4 to 20mA current loop. Data is transmitted by a loop powered HART® (Highway Addressable Remote Transducer) enabled smart transmitter. The Novato reference design uses the Maxim MAX11213 16-bit ADC to measure the resistance of the 2-, 3-, or 4-wire Resistance Temperature Detector (RTD) sensor. The current loop transmitter is built on the MAX5216 14-/16 bit DAC and the Maxim MAX9620 High-Efficiency 1.5MHz Op Amp. Calibration is easy by using the free Novato calibration software and the included USB-to-UART programming adapter.
The Maxim DS8500 HART modem chip meets HART Protocol Compatible physical layer requirements by providing the board’s digital interface to the HART protocol with a 4-20mA current loop. The Maxim MAX15006 40V Ultra-Low Quiescent-Current Linear Regulator and Maxim MAX6133 3ppm/°C, Low-Dropout Voltage Reference provide power and reference voltage to the entire circuitry.
The Novato reference design board provides a low-power, easy-to-use, reliable temperature measurement solution with a measured temperature range of -200°C to +850°C. Accuracy is better than 0.1% or 1.0°C, whichever is more accurate, over the entire operating range.
