GENERAL DES°RIPTION

The ADT7408 is specified for operation at supply voltages from

3.0 V to 3.6 V. Operating at 3.3 V, the average supply current is

less than 240 μA typical. The ADT7408 offers a shutdown mode

that powers down the device and gives a shutdown current of 3 μA

typical. The ADT7408 is rated for operation over the −20°C to

+125°C temperature range. The ADT7408 is available in a lead-

free, 8-lead LFCSP_VD, 3 mm × 3 mm (JEDEC MO-229 VEED-4)

package.

The ADT7408 is the first digital temperature sensor that complies

with JEDEC standard JC-42.4 for the mobile platform memory

module. The ADT7408 contains a band gap temperature sensor

and a 12-bit ADC to monitor and digitize the temperature to a

resolution of 0.0625°C.

There is an open-drain EVENT# output that is active when the

monitoring temperature exceeds a critical programmable limit or

when the temperature falls above or below an alarm window.

This pin can operate in either comparator or interrupt mode.

There are three slave device address pins that allow up to eight

ADT7408s to be used in a system that monitors temperature of

various components and subsystems.
