Intersil's "DAQ on a Stick" Provides Complete Thermocouple and Strain Gauge Reference Designs Using USB and EFM32 Gecko MCU

Demonstration at Embedded World 2013 Will Show Complete Signal Chain Solutions Using Intersil's Advanced Precision ICs With Microcontrollers

MILPITAS, CA--(Marketwire - Feb 22, 2013) -  Intersil Corporation (NASDAQ: ISIL), a leader in the design and manufacture of high-performance analog, mixed-signal and power management semiconductors, will demonstrate new thermocouple and strain gauge designs using a convenient "DAQ on a Stick" at Embedded World 2013.

The "DAQ on a Stick" is a reference design highlighting Intersil's precision products with different microcontrollers. The reference designs are self-contained demonstrations showing a complete signal chain solution using Intersil 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 ARM Cortex 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).

The software and demonstration videos can be downloaded or viewed from the Intersil website ( for the thermocouple reference design and ( for the strain gauge reference design. The solutions will be provided to customers by Avnet Memec.
