ADT75ARZ

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

Analog Devices 

GENERAL DESCRIPTION

The ADT75 is a complete temperature monitoring system in 8-lead

MSOP and SOIC packages. It contains a bandgap temperature sen-

sor and 12-bit 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 3 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 gives a shutdown current of typically 3 μA. The

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

temperature range.

Pin A0, Pin A1, and Pin A2 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.
