Evaluation boards are a great way to test and develop the performance of interconnected sensors and actuators. The MCP9800DM-PCTL sensor from Microchip Technology is one such device that can be used in conjunction with evaluation boards to measure temperature. From low temperatures up to higher temperatures of +125°C, the MCP9800DM-PCTL is a robust device that showcases the adjustable temperature characteristics of the unit, and can be used in industrial, automotive, and medical applications.

The MCP9800DM-PCTL is powered by an on-board 10-bit Analog-to-Digital Converter (ADC) that measures ambient temperatures from -55°C to +125°C with a resolution of 0.1°C (users can also select an optional resolution of 0.4°C). This temperature-sensing device was designed for easy circuit operation and quick time-to-market. The data sheet contains complete schematics and layout information that can be used to start evaluation board development.

The MCP9800DM-PCTL in an evaluation board consists of a 10-pin Mini-DIP form factor, which simplifies the design-in process and decreases the board size necessary for this component. This sensor’sMini-DIP form factor acts as an integrated header, allowing direct connection to test boards and also providing an exact physical reference for the placement of the sensor.

The MCP9800DM-PCTL has an adjustable temperature range to accommodate various application requirements. This device contains a 12-bit temperature register that can be updated with an averate frequency of up to 1 to 3 Hz. The temperature resolution of this device can be adjusted to either 0.1°C or 0.4°C.

The electrical characteristics of the MCP9800DM-PCTL are quite favorable too. The operating voltage range is 2.7V to 5.5V and the supply current is typically ± 200uA in normal operation. It also has an internal 2.048V reference that allow for precise temperature read-out, which is adjustable over a ±0.4°C range from the factory-calibrated set point.

The MCP9800DM-PCTL also features digital temperature compensation and alarm functions. The digital temperature compensation feature uses a separate 10-bit register to store offset values for each unit. These values can be adjusted to compensate for any inherent temperature errors due to device self-heating and environmental conditions, resulting in more accurate temperature readings. The alarm function allows temperature thresholds to be set, and if exceeded, an interrupt is generated by the device.

The MCP9800DM-PCTL also features an on-board temperature sensor that is calibrated from the factory for absolute temperature accuracy. It supports 16-bit I2C or SMBus communication protocol, which makes it easy to integrate with existing bus architectures. It also contains an integrated thermal shutdown feature to protect against over-temperature conditions.

Overall, the MCP9800DM-PCTL is a great fit for evaluation boards used to test and develop the performance of interconnected sensors and actuators. By using this temperature sensor in conjunction with evaluation boards, designers and engineers can reduce development time, improve the performance of their products, and create a more reliable and accurate sensing system.
