3 Description
The LMT86/LMT86-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 2.2V supply with
5.4 µA power consumption making it ideal for battery
powered devices. Package options including through-
hole TO-92 package allows the LMT86 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 LMT86/LMT86-
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 LMT86/LMT86-Q1 an alternative to
thermistors.
For devices with different average sensor gains and
comparable accuracy the LMT84/LM84-Q1,
LMT85/LMT85-Q1 and LMT87/LMT87-Q1 (For more
details see Comparable Alternative Devices.)
