Single-Channel Digital Output Temperature Solutions for HVAC
Last modified by Microchip on 2024/10/14 08:39
Digital Temperature sensors such as the MCP9808 provide greater design flexibility and simplicity for HVAC thermostat applications. Unlike resistance temperature detectors, these sensors do not require instrumentation circuit and circuit-calibration routines, while they do provide low power and superior accuracy. The MCP9808 provides a factory-calibrated maximum accuracy of ±0.5°C and programmable features such as a temperature window monitor output. If temperature exceeds the upper and lower temperature window plus hysteresis, the alert output asserts as an interrupt for microcontrollers or as a comparator for thermostat applications.
If you need to work with Microchip Support staff directly, you can submit a technical support case. Keep in mind that many questions can be answered through our self-help resources, so this may not be your speediest option.
