ADT75ARMZ

The ADT75ARMZ from Analog Devices is a 12-bit digital temperature sensor designed for accurate ambient temperature measurements. It provides a B grade accuracy of ±1.0°C from 0°C to 70°C and an A grade accuracy of ±2.0°C from -25°C to +100°C. The sensor operates with a supply voltage ranging from 2.7 V to 5.5 V and utilizes an SMBus/I2C-compatible interface.

With a measurable temperature range of -55°C to +125°C, the ADT75ARMZ is suitable for various applications including environmental control, computer thermal monitoring, and industrial process control. It offers a temperature resolution of 0.0625°C and includes features like an overtemperature indicator and a shutdown mode for low power consumption, reducing current draw to a typical 3 µA.

This temperature sensor is available in space-saving 8-lead MSOP and 8-lead SOIC packages. The MSOP package is offered in both Pb-Sn and Pb-free options, while the SOIC package is Pb-free. The device is supplied on a reel, with a standard package quantity of 1000 units, and is designed for surface mounting (SMD/SMT).

Key electrical specifications include a typical power consumption of 79 µW at 3.3 V and a typical operating supply current of 525 µA. The device supports connecting up to eight ADT75s to a single SMBus/I2C bus.
