ADT75
(Rev.:RevB)

±1°C Accurate, 12-Bit Digital Temperature Sensor

Analog Devices 

Data Sheet

GENERAL DESCRIPTION

The ADT75 is a complete temperature monitoring system in

8-lead MSOP and SOIC packages. It contains a band gap

temperature sensor and a 12-bit analog-to-digital converter

(ADC) to monitor and digitize the temperature to a resolution

of 0.0625°C. The ADT75 is pin and register compatible with the

LM75 and AD7416.

The ADT75 is guaranteed to operate at supply voltages from

2.7 V to 5.5 V. Operating at 3.3 V, the average supply current is

typically 200 µA.

ADT75

The ADT75 offers a shutdown mode that powers down the

device, and this mode gives a shutdown current of typically 3 µA.

The ADT75 is rated for operation over the −55°C to +125°C

temperature range.

The A0, A1, and A2 pins are available for address selection. The

OS/ALERT pin is an open-drain output that becomes active when

temperature exceeds a programmable limit. The OS/ALERT pin

can operate in either comparator or interrupt mode.
