Product Overview: LM40CIMTX/NOPB
The LM40CIMTX/NOPB is a precision integrated-circuit temperature sensor that can sense a -40 to +125 degrees Celsius temperature range while operating from a single 2.7V supply. Manufactured by Texas Instruments, the LM40's low supply current is less than 110µA at 5V and 50µA at 3V, making it ideal for battery-powered systems as well as general temperature monitoring.
This temperature sensor provides a linear output voltage that is directly proportional to the Celsius (Centigrade) temperature. The LM40 does not require any external calibration to provide typical accuracies of ±3°C at room temperature and ±4°C over a full -40 to +125°C temperature range. The low output impedance of the LM40 and its linear output make interfacing to readout or control circuitry especially easy.
The LM40 operates from a -40°C to +125°C temperature range and the LM40CIMTX/NOPB version comes in a small VSSOP-8 package, which is ideal for space-constrained applications. The device's quiescent current is also minimized over the full operating temperature range, which is particularly beneficial for portable and battery-powered applications.
The part number LM40CIMTX/NOPB indicates that this product is provided in a "No Lead" (Pb-free) package and is compliant with Texas Instruments' standards for RoHS compliance. This makes the LM40CIMTX/NOPB an environmentally friendly choice for temperature sensing needs.
