LM20 is a precision analog output CMOS integrated circuit temperature sensor that operates over a −55˚C to +130˚C temperature range.
The LM20 is a CMOS integrated‑circuit temperature sensor that operates from –55 °C to +130 °C. It provides an analog output voltage proportional to temperature and features low quiescent current (<10 µA) for minimal self‑heating.
The datasheet details electrical characteristics, mounting guidelines, recommended circuitry for capacitive loads, and application examples such as thermostats, power‑supply modules, and HVAC systems. Physical dimensions for the SC70 and micro‑SMD packages are also provided.
| Power Supply Voltage Range | +2.4 V to +5.5 V |
