Applications
The MCP9701AT-E/TT from Microchip Technology is a low-cost, low-power analog CMOS temperature sensor that provides a linear voltage output proportional to the measured temperature. The device features a 400mV DC offset at 0C, which allows reading negative temperatures without a negative supply. The output coefficient is 19.53mV/C, and the sensor provides an accuracy of +-2C over the 0C to +70C range. Operating from a single 2.4V to 5.5V supply, the MCP9701A consumes only 6uA typical, making it ideal for battery-powered applications. The sensor requires no external components and provides a direct analog interface to an ADC. The SOT-23-3 package minimizes board space, and the device is specified over the full -40C to +125C operating range with extended operation to +150C.
The MCP9701AT-E/TT operates through two main subsystems: (1) Temperature sensing element – A dedicated thermal sensing circuit using bipolar transistors generates a proportional-to-absolute-temperature (PTAT) voltage. The PTAT voltage increases linearly with temperature at a rate of approximately 19.53mV per degree Celsius. (2) Output conditioning – The raw PTAT voltage is amplified and combined with a 400mV DC offset to produce the final output voltage: VOUT = 400mV + (19.53mV/C x T). At 0C, the output is 400mV; at +25C, it is approximately 888mV; at +125C, it is approximately 2841mV. The 400mV offset allows reading negative temperatures on a single-supply ADC (at -40C, output = 400 + 19.53*(-40) = -181mV from 0C reference, but the 400mV offset keeps the output positive at 219mV). The entire circuit is implemented in CMOS, resulting in the ultra-low 6uA supply current.
