MCP9700AT-E/LT

The MCP9700AT-E/LT is a Linear Active Thermistor IC which converts temperature to analogue voltage. The device does not require an additional signal-conditioning circuit. The voltage output pin (VOUT) can be directly connected to the ADC input of a microcontroller. The device temperature coefficients are scaled to provide a 1°C/bit resolution for an 8-bit ADC with a reference voltage of 2.5V. When measuring relative change in temperature from +25°C, an accuracy of ±1°C (typical) can be realized from 0 to +70°C. This accuracy can also be achieved by applying system calibration at +25°C. In addition, this family is immune to the effects of parasitic capacitance and can drive large capacitive loads.

• 10mV/°C (typical) Optimized for ADC
• Optimized to drive large capacitive loads
• 6µA (typical) Low operating current
