LM35DZ Temperature Sensor TO-92 (Original)

The LM35 integrated circuit is a temperature sensor with reduced dimensions, it has a 3-pin TO-92 package. Its output is analog and linear with a slope of ZKEEP0Z /ºC. It allows you to measure temperature from −ZKEEP1Z to ZKEEP2Z, it will help you carry out applications such as thermometers, thermostats, monitoring systems and more. The LM35DZ is easy to use, it does not require additional circuitry to be used. It is powered directly from a ZKEEP3Z supply and delivers an analog output between ZKEEP4Z to ZKEEP5Z. This analog voltage can be read by the ADC of a microcontroller or development board such as Arduino, ESP32, Raspberry Pi Pico, PICs and more.

It is a very precise and easy to use electronic component, as it provides an analog signal directly proportional to the temperature in degrees Celsius. The LM35 is a passive temperature sensor, meaning it does not need any external power supply to operate. Instead, it uses the energy from the output signal to power itself, making it very efficient in terms of power consumption. The LM35 is very sensitive and can measure temperatures with an accuracy of ±0.5 degrees Celsius. It is very useful in applications where accurate temperature measurement is required, such as temperature control systems, security systems and measurement equipment.

Features

• Calibrated directly in Celsius with a scale factor of ZKEEP6Z/°C.
• Guaranteed accuracy of ±ZKEEP7Z at ZKEEP8Z and ±¾ °C over full –ZKEEP9Z to +ZKEEP10Z range.
• Operates from ZKEEP11Z to ZKEEP12Z without external components.
• Low quiescent current draw (< 60 µA) minimizes self-heating (< ZKEEP13Z in still air).
• Low output impedance (0.1 Ω for a ZKEEP14Z load) for easy interface to ADCs and microcontrollers.
• Nonlinearity typically ±¼ °C over full temperature span.
