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 2.0 × 2.0 mm DFN and a 1.6 × 1.6 mm

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.

the TMP1075 support up to 32 device addresses and

provides SMBus Reset and Alert function.
