If the ADC reference is not the same supply rail, the temperature reading drifts with Vcc. If the sensor is near a power MOSFET or regulator on the board, budget the self-heating error from the ~50 µA quiescent current into the copper pour under the SC-70-5. The SC-70-5 (SOT-353) package is a 5-lead, 0.65 mm pitch, roughly 2.0 mm × 2.1 mm footprint. The supplier device package is SC-70-5. There is no exposed thermal pad — the die is coupled to the board through the five leads only. For best accuracy, run a short, wide copper trace from the GND pin (pin 2) to a local ground plane pour under the package; this reduces the thermal resistance from the die to the board and minimizes self-heating error. The mounting type is surface mount, and the part is available in Tape & Reel (TR) or Cut Tape (CT) — the CT option is useful for prototype builds where you only need a few units.","metaTitle":"TMP235AQDCKTQ1 Automotive Temp Sensor, ±2.5°C, SC-70-5","metaDescription":"Texas Instruments TMP235AQDCKTQ1 analog temp sensor, AEC-Q100, ±2.5°C accuracy, 10mV/°C, -40°C to +150°C sensing range.
