Automotive-grade analog temperature sensing
The MCP9700T-E/LTVAO is an analog-output temperature sensor from Microchip Technology, qualified to AEC-Q100 Grade 1 for automotive applications. Its 10 mV/°C output slope provides a linear voltage proportional to temperature, readable directly by an ADC without external signal conditioning.
Accuracy and output scaling for BOM fit
This asymmetric tolerance at the extremes is typical for silicon bandgap sensors and must be budgeted into the system error stack for applications near the temperature limits. The 10 mV/°C scaling means a 25°C reading produces 0.75 V at the output pin (assuming a 0°C offset of 0.5 V typical for this family). No external reference or compensation is needed — the output drives directly into a microcontroller ADC input with a 0.1 µF bypass capacitor at the supply pin.
Package and sourcing posture
Supplied in a 5-lead SC-70-5 (SOT-353) package, the MCP9700T-E/LTVAO occupies minimal board area — suitable for dense ECU layouts where every square millimeter counts. The Tape & Reel packaging supports automated pick-and-place assembly for volume production. Microchip lists this device as Active in production.
