The device features +\/-0.5C accuracy over the 0 to +70C range with a linear 10mV\/C output slope and 500mV output at 0C, simplifying ADC-based temperature measurement. The 6uA supply current enables battery-powered applications, and no external components are required. The E suffix denotes extended temperature range (-40 to +125C), and TO denotes TO-92 through-hole package. The A variant offers improved accuracy compared to the non-A MCP9700.","working_principle":"The MCP9700A-E\/TO operates as a linear analog temperature sensor. (1) The internal bandgap voltage reference and proportional-to-absolute-temperature (PTAT) circuit generate a voltage that is linearly proportional to temperature. The output voltage follows Vout = 500mV + 10mV x T, where T is temperature in Celsius. This linear relationship eliminates the need for lookup tables or complex calibration required by thermistors. (2) The 10mV\/C output slope is designed to match the resolution of common ADCs: at 5V supply with a 10-bit ADC, each LSB represents approximately 0.5C (5V\/1024 = 4.88mV per LSB). Oversampling or using a higher-resolution ADC improves measurement resolution. (3) The 6uA supply current is achieved through a CMOS design that biases the bandgap and PTAT circuits at minimal current. The 800us start-up time ensures the output is valid within one ADC conversion cycle after power-up.","pin_description":"
