LM95172Q

Digital Temperature Sensor in Die Form with

±1°C Accuracy from 130°C to 160°C

General Description

Features

■

The LM95172Q is a digital temperature sensor with industry-

leading accuracy at temperatures up to 175°C. It features a

linear Sigma-Delta Analog-to-Digital Converter (ADC) with

fast conversion rates and low output noise. Communication

with the LM95172Q is achieved over an easy-to-use Serial

Peripheral Interface (SPI) with high noise immunity.

AEC-Q100 Grade 0 qualified and is manufactured on an

Automotive Grade Flow.

0.0625°C to 0.0078125°C temperature resolution

Wide −40°C to +175°C temperature range

35 ms conversion time tracks fast temp changes

OVERTEMP digital output switches when T_DIE> T_HIGH

The LM95172Q's resolution is user programmable from

0.0625°C to 0.0078125°C. When operating in 13-, 14- or 15-

bit resolution, the LM95172Q indicates a new conversion has

been completed. The LM95172Q also features an over-tem-

Shutdown mode saves power yet wakes up for one-shot

temperature update

The LM95172Q is specified for operation over the wide tem-

perature range of -40°C to 175°C. It is available in die form

which makes the LM95172Q ideal multi-chip modules or cus-

tom packaging to a wide variety of high-temperature applica-

tions.
