3 Description

The TMP1075 is the most accurate and lowest

power replacement to the industry standard LM75

and TMP75 digital temperature sensors. Available

in SOIC-8, VSSOP-8, WSON-8, and SOT563-6

packages, the TMP1075 offers pin-to-pin and

software compatibility to quickly upgrade any existing

xx75 design. The TMP1075 additional new packages

are a 2.0mm × 2.0mm DFN and a 1.6mm × 1.6mm

SOT563-6 reducing the printed circuit board (PCB)

footprint by 82% and 89% compared to the SOIC

package, respectively.

The TMP1075 has a ±1°C accuracy over a

wide temperature range and offers an on-chip 12-

bit analog-to-digital converter (ADC) providing a

temperature resolution of 0.0625°C.

Compatible with two-wire SMBus and I2C interfaces,

the TMP1075 support up to 32 device addresses and

provides SMBus Reset and Alert function.

The TMP1075 D, DGK, and DSG packages are

specified for operation over a temperature range of

−55°C to 125°C and the TMP1075N DRL package is

specified over the −40°C to 125°C temperature range.

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.
