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.
For devices with different average sensor gains and comparable accuracy the
LMT85/LM85-Q1, LMT86/LMT86-Q1 and LMT87/LMT87-Q1.
