Temperature sensors are devices that measure temperature, and they come in two varieties — Analog and Digital Output. The LM34CZ/NOPB is one of the most commonly used temperature sensors that belongs to Analog and Digital Output classification. This guide is a comprehensive overview of the LM34CZ/NOPB application field and working principle.

Application

The LM34CZ/NOPB is a linear scale factor temperature sensor. It is ideal for temperature sensing applications in automotive, industrial, process control, and consumer products because of its n-channel MOSFET output. LM34CZ/NOPB can accurately sense temperature with a linear relationship between sensed temperature and sensed voltage. It provides good accuracy over its temperature range of -55°C to +150°C and a comparatively low power consumption. For its fast response time and low power consumption, it is excellent for industrial & commercial applications.

The device comes in two packages – TO-92 and SOT-23, and has both a voltage output and a current output. The voltage output pin of the device has an output range from 0V to 5V, while the current output pin has an output range of 2mA to 7mA. These features make it suitable for multiple applications including automotive, HVAC/R, and domestic appliances.

Working Principle

The LM34CZ/NOPB comprises two major components — a sealed semiconductor die and a sealed package. Inside the die, the LM34CZ/NOPB has a temperature-sensitive PN-junction with a large junction area that minimizes undesired base spreading. This ensures that temperature variations will not adversely affect the output voltage. The voltage output is consistent in the temperature range of -55°C to +150°C for LM34CZ/NOPB.

In the current output version, the conductor-filled die is connected to an external current source. This causes current to flow through the die, producing a voltage across it whose magnitude is proportional to temperature. This temperature-dependent voltage is then amplified and converted into the desired current.

The LM34CZ/NOPB is optimized for low power consumption and fast response time. The onboard circuitry limits the amount of power consumed by the device by controlling the current according to the sensed temperature. This ensures that the device draws minimal power when not sensing temperature, and also ensures that the device draws more power when sensing temperature, thus providing fast response time.

The LM34CZ/NOPB also comes with an onboard temperature protection circuit. This protects the device from excessive temperatures that may damage the device, thus providing maximum reliability and performance.

Overall, the LM34CZ/NOPB is an excellent temperature sensor for both commercial and industrial applications. It provides good accuracy over its temperature range and is capable of providing fast response times and low power consumption. Its temperature protection circuit ensures maximum reliability and performance.
