GENERAL DESCRIPTION
The ADT7401 is a complete temperature monitoring system
that outputs a 12-bit digital word corresponding to the temp-
erature of the ADT7401’s silicon. The device offers a high
temperature accuracy of ±1°C from 0°C to +70°C, with
excellent transducer linearity. The digital output of the
ADT7401 is SMBus/I2C compatible.
The ADT7401 is specified for operation at supply voltages from
2.7 V to 5.5 V. Operating at 3.3 V the supply current is typically
230 A.
The ADT7401 is rated for operation over the -40°C to +150°C
temperature range. It is packaged in a low cost, low area SOT-23
package and mini-SOIC package. The SMBus ALERT pin is an
open-drain output that is used as an out of limit temperature
indicator. It can be wired-AND with other SMBus ALERT pins
and is used in conjunction with the SMBus General Call
Address.
The DC (Daisy Chain) pin creates a sub-SMBus/I2C bus where
a multiple of ADT7401’s can be used. The DC pin has the
advantage of freeing up the address options on the root bus as
only one ADT7401 root address needs to be used by the
SMBus/I2C controller but still being able to address a number of
ADT7401 temperature sensors.
PRODUCT HIGHLIGHTS
1.
The ADT7401 has an 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 5.5 V.
3.
Space-saving 6-lead SOT-23 package and 8-lead MSOP.
4.
Temperature accuracy of ±0.5°C.
5.
0.0625°C temperature resolution.
6.
The ADT7401 features a one shot mode that reduces the
power consumption to 2.57 W at one sample per second.
