The “DAQ on a Stick” is a reference design highlighting the company's precision products with different microcontrollers. The reference designs are self-contained demonstrations showing a complete signal chain solution using the company's parts and an Energy Micro EFM32 Leopard Gecko microcontroller. The complete reference designs are housed in a USB stick form factor.
This compact design enables the user to power the application through the USB port and monitor the temperature through the GUI interface on a computer. The solutions feature a variety of Intersil ICs, including the ISL28134 low noise, zero-drift op-amp, the ISL26102 24-bit delta sigma converter, and the ISL21010 precision bandgap voltage reference. The Energy Micro EFM32LG332F128 is an extremely energy efficient 32-bit ARCortex MCU. The thermocouple application circuit is calibrated at 25°C to within ± 0.1°C using a Fluke 54II Thermometer. The accuracy of this design is down to ±0.75% (limits of error).(Contact company for pricing and availability)
