The LMT84/LMT84-Q1 are precision CMOS integrated-circuit temperature sensors with an analog output voltage that is linearly and inversely proportional to temperature. Its features make it suitable for many general temperature sensing applications. It can operate down to 1.5V supply with 5.4 µA power consumption making it ideal for battery powered devices. Package options including through-hole TO-92 package allows the LMT84 to be mounted on-board, off-board, to a heat sink, or on multiple unique locations in the same application. A class-AB output structure gives the LMT84/LMT84-Q1 strong output source and sink current capability that can directly drive up to 1.1 nF capacitive loads. This means it is well suited to drive an analog-to-digital converter sample-and-hold input with its transient load requirements. It has accuracy specified in the operating range of −50°C to 150°C. The accuracy, 3-lead package options, and other features also make the LMT84/LMT84-Q1 an alternative to thermistors.
