GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

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.

1. On-chip temperature sensor that allows an accurate

measurement of the ambient temperature. The measurable

temperature range is −40°C to +150°C.

2. Supply voltage of 2.7 V to 5.25 V.

The ADT7301 has a flexible serial interface that allows easy

interfacing to most microcontrollers. The interface is compati-

ble 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. Exposure beyond this

limit affects device reliability.

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

4. Typical temperature accuracy of 0.5°C.

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

6. Shutdown mode that reduces the power consumption to

4.88 μW with V_DD= 3.3 V @ 1 SPS.

7. Compatible with AD7814.
