FEATURES

GENERAL DES°RIPTION

Qualified for automotive applications

High performance

Temperature accuracy:

1ꢀ° from −55ꢀ° to +175ꢀ° (2.7 V to 3.3 V)

16-bit temperature resolution: 0.0078ꢀ°

The ADT7312 is a 1ꢀ° aꢁꢁurate digital temperature sensor

that operates over a very wide temperature range of −55ꢀ° to

+175ꢀ° and is available in die form only. It ꢁontains an internal

band gap referenꢁe, a temperature sensor, and a 16-bit analog-

to-digital ꢁonverter (AD°) to monitor and digitize the temper-

Fast first temperature conversion on power-up of 6 ms

Easy implementation

No temperature calibration or correction required

No linearity correction required

Low power

Power-saving 1 sample per second (SPS) mode

880 μW typical at 3.6 V in normal mode

9 μW typical at 3.6 V in shutdown mode

Wide operating ranges

Temperature range: −55ꢀ° to +175ꢀ°

Voltage range: 2.7 V to 5.5 V

ature to a resolution of 0.0078ꢀ°. The default AD° resolution

is 13 bits (0.0625ꢀ°). The AD° resolution ꢁan be ꢁhanged to

16 bits (0.0078ꢀ°) using the serial interfaꢁe.

The ADT7312 is guaranteed to operate over supply voltages

from 2.7 V to 5.5 V. At 3.6 V operation, the average supply

ꢁurrent is typiꢁally 245 μA. The ADT7312 has a shutdown

mode that powers down the deviꢁe, resulting in a typiꢁal

shutdown ꢁurrent of 2.5 μA at 3.6 V. The ADT7312 is rated

for operation over the −55ꢀ° to +175ꢀ° temperature range.

The °T pin is an open-drain output that beꢁomes aꢁtive when

the temperature exꢁeeds a programmable ꢁritiꢁal temperature

limit. The default ꢁritiꢁal temperature limit is 147ꢀ°. The INT

pin is also an open-drain output that beꢁomes aꢁtive when the

temperature exꢁeeds a programmable limit. The INT pin and

the °T pin ꢁan operate in either ꢁomparator or interrupt mode.

Programmable interrupts

°ritical overtemperature interrupt

Overtemperature/undertemperature interrupt

SPI-compatible interface

Available in die form only

PRODU°T HIGHLIGHTS

APPLI°ATIONS

1. Ease of use, no ꢁalibration or ꢁorreꢁtion required.

2. Low power ꢁonsumption.

3. Exꢁellent long-term stability and reliability.

4. Qualified for automotive appliꢁations.
