概要
説明
This reference design shows the operation of Renesas' precision products in a temperature sensor application. The application uses Renesas' data acquisition (DAQ) on a stick reference design that has been modified to work with a Semitec 103AP-2 RTD temperature sensor. The system operates over the temperature range of -60 °C to +150 °C. It has an accuracy of ±1 °C or better.
The reference design is a self-contained demo showing a complete signal chain solution from the Semitec sensor to the signal conditioning components consisting of a Vishay precision resistor and Renesas precision parts, a Renesas RL78/G1C microcontroller and a graphical user interface (GUI). The image to the right shows the DAQ on a stick connected to the external Semitec temperature sensor.
The complete reference design is conveniently housed in a USB stick form factor with plug-in connection for the temperature sensor. This compact design draws power through the USB port and uses a GUI to display the real-time temperature readings from the temperature sensor onto the computer.
The image below shows a simplified block diagram of the temperature sensor design. The design uses a Semitec 103AP-2 thermistor, a Vishay Precision Group 500Ω ±0.1% precision resistor, Renesas' ISL28634 instrumentation amplifier (in amp), ISL21090 2.5V precision voltage reference, ISL21010 4.096V precision voltage reference, ISL21010 3.3V precision voltage reference, the ISL26104 24-bit Delta-Sigma converter, ISL22316 digitally controlled potentiometer (DCP), and an R5F10JBC (RL78/G1C) microcontroller.
The installation application includes the following items:
- GUI software
- Desktop shortcut for easy access
- Application note and schematics
