GENERAL DESCRIPTION
The ADT7302 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.
The ADT7302 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 ADT7302’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.
PRODUCT HIGHLIGHTS
1.
The ADT7302 has an on-chip temperature sensor that
allows an accurate measurement of the ambient tempera-
ture. The measurable temperature range is −40°C to
+125°C.
Supply voltage of 2.7 V to 5.5 V.
Space-saving 6-lead SOT-23 and 8-lead MSOP packages.
Temperature accuracy of ±2°C.
13-bit temperature reading to 0.03125°C resolution.
The ADT7302 features a shutdown mode that reduces the
power consumption to 4.88 µW with V
DD
= 3.3 V @ 1 SPS.
