The LMT87 and LMT87-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 2.7-V supply
with 5.4-µA power consumption. Package options including through-hole TO-92 package allows the
LMT87 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 LMT87 and LMT87-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 LMT87 and LMT87-Q1 an alternative to
thermistors.
For devices with different average sensor gains and comparable accuracy, the
LMT84/LM84-Q1, LMT85/LMT85-Q1, and LMT86/LMT86-Q1 (For more details, see Table 2.)
