Why the 10 mV/°C scale factor simplifies your BOM
The LM35CZ/NOPB outputs an analog voltage that scales linearly at 10mV/°C, so 25°C reads 250 mV, 100°C reads 1.0 V. Because the output is already calibrated in °C, no external voltage reference or cold-junction compensation is needed — the ADC in your MCU reads temperature directly.
Accuracy at 25°C vs. the full temperature window
The headline accuracy is ±1°C at 25°C test condition. For a system that must hold ±2°C from cold start to hot enclosure, stack the 25°C offset plus the temperature-coefficient error, not just the 25°C number.
Supply compliance — 4V to 30V covers industrial rails
The LM35CZ/NOPB operates from a 4V to 30V supply. That range covers 5V logic rails, 12V industrial buses, and 24V panel supplies without a local voltage regulator. The quiescent current is low enough (typically 60 µA) that self-heating is negligible — less than 0.1°C in still air.
For new designs, this removes the single-source risk that comes with NRND or EOL sensors.
Through-hole TO-92 — footprint and assembly fit
The LM35CZ/NOPB comes in a TO-226-3 / TO-92-3 through-hole package. The three leads (Vcc, GND, Vout) fit a standard 0.100-inch pitch footprint. The package is supplied in Box — typically bulk tubes or ammo pack, not tape-and-reel. For wave-solder or hand-assembly lines this is straightforward; for reflow-only lines, consider the SMD sibling LM35DM.
