LM57CISD-10/NOPB Sensors, Transducers

Temperature sensors are devices designed to accurately measure the temperature of a given environment or object. These sensors include thermocouples, resistance temperature detectors, thermistor temperature sensors, and solid state thermometric sensors.

Among solid state thermometric sensors, the LM57CISD-10/NOPB is a thermistor-based device intended for temperature sensing. It uses a NTC (Negative Temperature Coefficient) type thermistor, which is a thermally sensitive resistor. The thermistor’s resistance changes with the temperature, allowing the output voltage to indicate temperature.

The LM57CISD-10/NOPB has an operating range of -55 °C to +125 °C. It is made up of a standard 2-pin SOT-23 package and design, with a built-in 10-k⋅Ω thermistor. It operates on a bipolar power supply voltage from 2.7V to 12V.

The working principle behind the LM57CISD-10/NOPB operates on the thermistor\'s resistance to temperature. Essentially, the device produces an output voltage level that depends on the resistance of the thermistor. As temperature changes, so does the resistance of the thermistor, which then changes the output voltage. A trans-resistance amplifier, or voltage-to-current converter, in the device measures the thermistor’s resistance and changes it back into a voltage signal.

The LM57CISD-10/NOPB has a wide range of applications. Its small size makes it ideal for box, PCB, and on-chip applications. It is typically used where a wide operating temperature range is required. Other typical applications include electronic cooling systems, automotive, HVAC, medical, and industrial temperature sensing. They are also used for temperature-compensated circuits, analog-to-digital converters, and data-acquisition modules.

The LM57CISD-10/NOPB is an excellent thermistor-based solid state temperature sensor. It is dependable, small, and can be used in a variety of applications. The device offers ease of use, low power consumption, and accurate temperature measurement when compared to other temperature sensors on the market.
