GENERAL DESCRIPTION

The ADT7301 is a complete temperature monitoring system

available in SOT-23 and MSOP packages. It contains a band gap

temperature sensor and a 13-bit ADC to monitor and digitize

the temperature reading to a resolution of 0.03125°C.

PRODUCT HIGHLIGHTS

1. The ADT7301 has an on-chip temperature sensor that

allows an accurate measurement of the ambient tempera-

ture. The measurable temperature range is −40°C to

+150°C.

The ADT7301 has a flexible serial interface that allows easy

interfacing to most microcontrollers. The interface is compat-

ible with SPI®, QSPI™, and MICROWIRE™ protocols as well as

DSPs. The part features a standby mode that is controlled via

the serial interface. The ADT7301’s wide supply voltage range,

low supply current, and SPI compatible interface make it ideal

for a variety of applications, including personal computers,

office equipment, automotive, and domestic appliances. The

ADT7301 is rated for operation over the -40°C to +150°C

temperature range. It is not recommended to operate the device

at temperatures above +125°C for greater than a total of 5%

(5,000 hours) of the lifetime of the device. Any exposure

beyond this limit will affect device reliability.

2. Supply voltage of 2.7 V to 5.5 V.

3. Space-saving 6-lead SOT-23 and 8-lead MSOP packages.

4. Temperature accuracy of 0.5°C.

5. 13-bit temperature reading to 0.03125°C resolution.

6. The ADT7301 features a shutdown mode that reduces the

power consumption to 4.88 µW with V_DD= 3.3 V @ 1 SPS.
