LMT85, LMT85-Q1

SNIS168C –MARCH 2013–REVISED OCTOBER 2015

LMT85/LMT85-Q1 SC70/TO-92, Analog Temperature Sensors with Class-AB Output

1 Features

3 Description

The LMT85/LMT85-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 1.8V supply with

5.4 µA power consumption making it ideal for battery

powered devices. Package options including through-

hole TO-92 package allows the LMT85 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 LMT85/LMT85-

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 LMT85/LMT85-Q1 an alternative to

thermistors.
