AD7817BRZ +BOM

Temperature sensor with integrated on-chip functionality and 4-channel capability

AD7817BRZ Allgemeine Beschreibung

The AD7817BRZ digital temperature sensor by Analog Devices Inc. offers high precision temperature measurement with its 10-bit ADC, providing accurate readings from -40°C to +105°C with a resolution of 0.25°C. Its factory calibration ensures exceptional accuracy, eliminating the need for additional calibration in most scenarios. The on-chip oscillator and sequencer simplify the conversion process, enhancing its usability in diverse systems. Utilizing a 2-wire serial interface (I2C) to communicate with the microcontroller, it boasts a programmable address for connection of multiple sensors on the same bus. With a wide voltage range of 2.7V to 5.5V, it can adapt to various power supply setups. In addition, its standby mode minimizes power consumption during inactive periods, making it ideal for battery-powered applications. The built-in fault detection and watchdog timer further enhance system reliability
