The DAQ on a Stick Renesas Thermocouple is one of a series of reference designs highlighting Renesas' precision products with different microcontrollers. This reference design is a self-contained demo showing a complete signal chain solution using Renesas precision parts and a Renesas microcontroller. The complete reference design is conveniently housed in a USB stick form factor. This compact design draws power through the USB port and uses a graphical user interface (GUI) to display the real-time temperature. The image to the right shows the data acquisition (DAQ) on a stick reference design.
The image below shows a simplified schematic of the thermocouple design. The design uses Renesas' ISL28134 chopper amplifier, ISL22317 precision digitally controlled potentiometer (DCP), ISL21010 4.096V voltage reference, ISL21010 3.3V voltage reference, the ISL26102 24-bit Delta-Sigma converter, and the R5F10JBC (RL78/G1C) microcontroller.
The installation application includes the following items:
- GUI software
- Desktop shortcut for easy access
- Application note and schematics
