3 Description

The TMP1075 is a lower power, higher accuracy

replacement to the industry standard LM75 and

TMP75 digital temperature sensors. Available in

SOIC-8 and SOP-8 packages, the TMP1075 offers

pin to pin and software compatibility to quickly

upgrade any existing xx75 design. New with the

TMP1075 is an optional 2x2mm DFN package

reducing the PCB footprint by 79% compared to an

SOIC package.

The TMP1075 provides a 25% improvement in

accuracy over standard xx75 temperature sensors

and

offers

an

on-chip

12-bit

analog-to

digital

converter (ADC) providing a temperature resolution of

0.0625°C.

the TMP1075 supports up to 32 devices address and

provides SMBus Alert.

The TMP1075 devices are ideal for temperature

measurement

in

a

variety

of

communication,

computer, consumer, environmental, industrial, and

instrumentation applications.

The TMP1075 devices are specified for operation

over a temperature range of

−55°C to +125°C.

The TMP1075 units are 100% tested on a production

setup that is NIST traceable and verified with

equipment that is calibrated to ISO/IEC 17025

accredited standards.
