Description

The ADT7301 is a complete temperature monitoring system 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 ADT7301 has a flexible serial interface that allows easy interfacing to most microcontrollers. The interface is compatible with SPI?, QSPI and MICROWIRE? protocol and is also compatible with 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. TheADT7301 is rated for operation over the ?40?C to +150?Ctemperature range. It is not recommended to operate the deviceat temperatures above +125?C for greater than a total of 5% (5,000 hours) of the lifetime of the device. Exposure beyond thislimit affects device reliability.PRODUCT HIGHLIGHTS On-chip temperature sensor that allows an accurate measurement of the ambient temperature. The measurable temperature range is ?40?C to +150?C. Supply voltage of 2.7 V to 5.25 V. Space-saving 6-lead SOT-23 and 8-lead MSOP packages. Typical temperature accuracy of ?0.5?C. 13-bit temperature reading to 0.03125?C resolution. Shutdown mode that reduces the power consumption to 4.88 ?W with VDD = 3.3 V @ 1 SPS. Compatible with AD7814.APPLICATIONS Medical equipment Automotive Environmental controls Oil Temperature Hydraulic systems Cellular phones Hard disk drives Personal computers Electronic test equipment Office equipment Domestic appliances Process control
