The demo board is a complete stand-alone smoke detector application with a smoke chamber emulator. The demo board allows evaluation of all the functions of the RE46C190. Key test points of the device are available at the bottom edge of the demo board. It is designed for battery operation using a CR123A battery or can be operated using a power supply. The RE46C190 application circuit is on the right side of the board by the battery holder and piezo horn and the smoke chamber emulator is on the left. The smoke chamber emulator can be disconnected from the application circuit and a photo smoke chamber or its components can be connected to the demo board.

Devices Supported: RE46C190

The RTD Reference Design demonstrates how to instrument Resistive Temperature Detector (RTD) and accurately measure temperature. This solution uses the MCP3551 22-Bit Analog to Digital Converter (ADC) to measure voltage across the RTD. The ADCand the RTD are referenced using an onboard reference voltage and the ADC inputs are directly connected to the RTD terminals. This provides a ratio metric temperature measurement. The solution uses a current limiting resistor to bias the RTD. It providesa reliable and accurate RTD instrumentation without the need for extensive circuitcompensation and calibration routines.

In addition, this reference design includes a silicon temperature sensor, MCP9804. This sensor is used for comparison only, it is not needed to instrument an RTD. The MCP3551 and MCP9804 outputs are read using a USB PIC® MCU. This controller is also connected to a PC using a USB interface. The Thermal Management software is used to plot the RTD temperature data in stripchart format.

Devices Supported: MCP3551, MCP9804
