3 Description
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 .)
