The LM61CIZ/NOPB is a precision integrated-circuit temperature sensor from Texas Instruments, known for its high precision and reliability. This sensor measures temperatures from -30°C to +100°C and provides a linear voltage output that is directly proportional to the Celsius temperature. The sensor's output impedance is low, allowing it to drive large loads easily, and the quiescent current is low, making it ideal for battery-powered applications. The LM61CIZ/NOPB provides typical accuracies of ±1/4°C at room temperature and ±3/4°C over the full temperature range without requiring external calibration or trimming. It is available in a compact, 8-pin package, ensuring it is space-efficient. The wide operating voltage range of 2.7V to 10V makes it adaptable to various power supply conditions. Overall, the LM61CIZ/NOPB is an efficient and accurate temperature sensor suitable for a variety of environments and applications.
