Description:
The LM35 Temperature Sensor stands out as a precision integrated circuit designed for analog temperature sensing, delivering an output voltage that scales linearly with temperature, measured directly in degrees Celsius. This sensor is engineered to provide highly accurate temperature readings without necessitating any external calibration or trimming, simplifying its integration into various electronic systems. Its low output impedance ensures a stable and reliable signal, while its precisely calibrated linear response facilitates straightforward interpretation of the output.
A key advantage of the LM35 lies in its direct compatibility with analog-to-digital converters (ADCs). Specifically, it interfaces seamlessly with 10-bit and 12-bit ADCs, eliminating the need for additional signal conditioning components. The sensor's output, which increases by 10 millivolts for every degree Celsius rise in temperature, aligns perfectly with the typical input range of these ADCs. However, when paired with 8-bit ADCs, such as the ADC0808 or ADC0804, an amplifier is required to amplify the signal, enabling the detection of temperature variations as small as 1°C.
