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癈.
The ADT7302 has a flexible serial interface that allows easy
interfacing to most microcontrollers. The interface is compatible
with SPI? QSPI", and MICROWIRE" protocols as well as DSPs.
The part features a standby mode that is controlled via the serial
interface.
The ADT7302s wide supply voltage range, low supply current,
and SPI-compatible interface make it ideal for a variety of
applications, including PCs, office equipment, automotive, and
domestic appliances.
PRODUCT HIGHLIGHTS
1. On-chip temperature sensor that allows an accurate
measurement of the ambient temperature. The measurable
temperature range is 40癈 to +125癈.
2. Supply voltage of 2.7 V to 5.25 V.
3. Space-saving 6-lead SOT-23 and 8-lead MSOP packages.
4. Maximum temperature accuracy of ?癈.
5. 13-bit temperature reading to 0.03125癈 resolution.
6. Shutdown mode that reduces the power consumption to
4.88 糤 with VDD = 3.3 V at 1 SPS.
7. Compatible with AD7814.
