Temperature Sensors - Analog and Digital Output are used to measure temperatures in a wide range of settings, including medical, industrial, automotive, and aerospace applications. One example of a temperature sensor is the LM95214CISDX/NOPB, which is designed for a wide variety of applications, from HVAC systems to medical instruments.

The LM95214CISDX/NOPB is a digital temperature sensor that communicates over I2C. This sensor uses a microfabricated thermistor for the temperature sensing element, and it offers both an analog and a digital output. The analog output of the device is provided through a voltage divider composed of two external resistors, which allows for an output voltage between 0 and 0.5V. The digital output is generated in a serial protocol bus that provides data at up to 5MHz.

The LM95214CISDX/NOPB can measure temperatures ranges from -40°C to +125°C—well beyond the range for most thermistors but within the range for the integrated thermistor on the device. Temperature accuracy is typically ±1°C throughout the range. It is also designed for high noise immunity and power throughput. The LM95214CISDX/NOPB is available in a variety of packages, including 14-pin plastic DIP and SOIC packages.

The LM95214CISDX/NOPB uses a linearization algorithm to convert the thermistor’s response to an accurate output signal. The digital output of the device is an 8-bit result representing the temperature within the range of -40°C to +125°C. The output of the device is then converted to an analog signal by using a voltage divider composed of two external resistors. The voltage divider converts the temperature signal from the device to a voltage between 0 and 0.5V.

In addition to its main analog and digital temperature sensing applications, the LM95214CISDX/NOPB can also be used for fan speed control, monitoring, and/or temperature settings within HVAC systems; for medical instrumentation, such as monitoring the temperature of critical components in implants and prostheses; or in automotive and aerospace applications. Versions of the device are also available for use in hazardous area locations.

The LM95214CISDX/NOPB is widely used in a wide range of applications due to its simple design, easy-to-use digital protocol, and its wide temperature range and accuracy. Its two-wire interface and low-power design make it an ideal choice for many applications requiring temperature sensing.
