ADM1021AARQZ-R is a performance-based precision digital temperature monitoring IC manufactured by Analog Devices Inc. It is a small multifunction thermal management device that gives designers flexibility and has a wide range of applications.This reliable IC has a wide operating temperature range (-40°C to+125°C) and low power consumption. It operates with supply voltages up to 5.5V with a resolution of up to 9-bits. This high accuracy and wide operating temperature range make it ideal for applications such as thermal sensing, temperature control, and thermal protection. The device measures temperature by comparing the temperature of a sensor to reference voltage (an internal voltage reference or an external voltage reference). An on-chip 10-bit ADC allows the device to measure temperature with an accuracy of up to ±1°C. The ADM1021AARQZ-R can be used in a variety of applications. It is ideal for high-end automotive and consumer electronics applications, as it can accurately measure and monitor temperature over a wide range of temperatures.The IC provides 4-bit programmable address and 0-3 volt reference voltage input. It also has integrated thermal protection functions, including overtemperature shutdown, overtemperature latch, and overtemperature warning. The integrated overtemperature warning and overtemperature latch features are designed to alert users when the temperature begins to exceed desired levels, while the overtemperature shutdown feature prevents the device from over-stressing.This IC supports an invocation interface via an I2C™ port, providing an easy interface for digital applications. With its integrated temperature sensor, the device can be used in applications such as in-vehicle temperature control, fan speed control, thermal protection, and temperature sensing. The ADM1021AARQZ-R also supports programmable alerts and other modes of operation, such as programmable over- voltage, under-voltage, and over-current alerts. This helps to prevent device failures and catastrophic failures due to thermal issues, in addition to making it ideal for use in safety-critical applications.The interface pins of the device are compatible with the industry-standard I2C™ protocol. The device is available in a compact 5-mm × 5-mm, 24-pin QFN package, making it ideal for space-constrained applications.The ADM1021AARQZ-R provides a low-cost, high-performance solution for temperature monitoring and management. Its wide operating temperature range and low power consumption make it ideal for a variety of applications, including automotive, aerospace, and medical. This IC is an important part of system-level thermal management, and it helps to ensure the reliability and safety of the system.
