RTKA-BDGSTKEV2Z
Description
The DAQ on a Stick Renesas Strain Gauge 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 voltage readings from a bridge strain gauge or a user supplied sensor. The board image to the right shows the data acquisition (DAQ) on a stick connected to an external foil strain gauge.
The image below shows a simplified schematic of the strain gauge design. The design uses Renesas’ ISL28134 chopper amplifier, ISL22316 digitally controlled potentiometer (DCP), ISL43840 dual 4-channel multiplexer (Mux) configured as a differential Mux, ISL21010 4.096V voltage reference, ISL21010 3.3V voltage reference, the ISL26102 24-bit Delta-Sigma converter, and the R5F10JBC (RL78/G1C) microcontroller.
