FEATURES

GENERAL DESCRIPTION

13- or 16-bit user selectable temperature-to-digital converter

Temperature accuracy 0.ꢀ°C from −40°C to +10ꢀ°C

No temperature calibration/correction required by user

Power saving 1 sample per second (SPS) mode

Fast first conversion on power-up of 6 ms

SPI-compatible interface

Operating temperature from −ꢀꢀ°C to +1ꢀ0°C

Operating voltage: 2.7 V to ꢀ.ꢀ V

The ADT7310 is a high accuracy digital temperature sensor

in a narrow SOIC package. It contains a band gap temperature

reference and a 13-bit ADC to monitor and digitize the

temperature to a 0.0625°C resolution. The ADC resolution,

by default, is set to 13 bits (0.0625 °C). This can be changed

to 16 bits (0.0078 °C) by setting Bit 7 in the configuration

The ADT7310 is guaranteed to operate over supply voltages from

2.7 V to 5.5 V. Operating at 3.3 V, the average supply current is

typically 210 μA. The ADT7310 has a shutdown mode that

powers down the device and offers a shutdown current of

typically 2 μA. The ADT7310 is rated for operation over the

−55°C to +150°C temperature range.

Critical overtemperature indicator

Programmable overtemperature/undertemperature interrupt

Low power consumption: 700 μW typical at 3.3 V

Shutdown mode for lower power: 7μW typical at 3.3 V

8-lead narrow SOIC RoHS-compliant package

APPLICATIONS

The CT pin is an open-drain output that becomes active when

the temperature exceeds a programmable critical temperature

limit. The default critical temperature limit is 147°C. The INT

pin is also an open-drain output that becomes active when the

temperature exceeds a programmable limit. The INT and CT

pins can operate in either comparator or interrupt mode.
