DAQ on a Stick, Strain Gauge with Programmable Chopper Stabilized IN-Amp

Introduction

The “DAQ on a Stick, Strain Gauge with Programmable INAMP” is one of a series of reference designs highlighting Intersil’s precision products with different microcontrollers. This reference design is a self contained demo showing a complete signal chain solution using Intersil 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. Figure 1 shows the Data Acquisition DAQ on a Stick connected to an external foil strain gauge.

Figure 2 shows a simplified schematic of the Strain Gauge design. The design uses Intersil’s ISL28634 Programmable Instrumentation Amplifier INAMP , ISL23328 Digital Potentiometer, ISL28233 Operational Amplifiers, ISL43741 Differential Mux, ISL21010 Voltage Reference, the ISL26104 24-bit Delta Sigma Converter and Renesas R5F10JBC RL78/G1C Microcontroller.

Application Note 1853

Running the Evaluation Software

After software has been installed, and the setup screen in Figure 5 appears, plug the ISLRE-BDGSTKEV1Z board into a USB port on the computer.

The green LED on the DAQ on a Stick board should be on at this time. When the software starts, the Startup Screen shown in Figure 5 will appear. With the DAQ on a Stick connected, the USB Status indicator will display “Connected 0x2033”. The assigned HID PID code for this application is 0x2033. This is verification the software is communicating with the board.

If the DAQ on a Stick is not connected, or a problem exists with the demo, the message will read “HID Device Not Found”. If this occurs, click on the “Test USB Connection” button to see if this enables the connection. If not, try disconnecting and re-connecting the device or restarting the software.

From the Startup Screen Figure 5 , the user can click on the Instantaneous Voltage button to get a single voltage reading, select the sensor input they want to measure and adjust the gain of the amplifier, or click the Start button to go to the Measurement Display screen, as shown in Figure 6, “GUI MEASUREMENT SCREEN,” on page At this point the green LED on the board will go off.

For future use of the software, click on the Intersil DAQ shortcut created in the previous step on the desktop. Figure 3 shows the desk top icon.

Connecting the Sensor

The ISLRE-BDGSTKEV1Z reference design gives the user the option to measure the strain on an internal Bridge with a foil gauge supplied with the evaluation board or connect an external sensor and monitor the voltage reading on the GUI screen. The user will select the “Supplied with the Demo” sensor or “Customer Supplied” sensor by clicking the appropriate radial button at the top of Figure The “Supplied with the Demo” sensor foil gauge is the default value in the GUI with a gain of 100V/V. Figure 5 shows the external connector inputs, which are used to connect the sensor to the circuit shown in Figure 2 on page
