Overview
The LM61BIZ/NOPB is a precision, integrated-circuit temperature sensor produced by Texas Instruments. This device is capable of sensing a wide temperature range from –30°C to 100°C while operating from a single 2.7-V to 10-V supply. The LM61 features a linear output voltage that is proportional to temperature, with a 10 mV/°C slope and a 600 mV DC offset, allowing for the measurement of negative temperatures without the need for a negative supply.
The sensor is available in a TO-92 package and is suitable for remote applications due to its low power consumption and high accuracy. It is UL recognized and has a low self-heating effect, making it ideal for various temperature-sensing applications.
