Product Introduction

Overview

The AD7416ARM, produced by Analog Devices Inc., is a temperature-monitoring device designed for precise ambient temperature measurement. This component is part of the AD7416 series and is housed in an 8-lead package, such as 8-TSSOP or 8-MSOP. It is specifically tailored for applications requiring accurate temperature sensing and is a superior replacement for the LM75 temperature sensor. The device operates on a wide supply range of 2.7 V to 5.5 V, making it versatile for various power environments.

Key Features

  • I2C-Compatible Serial Interface: Allows for easy communication and integration with other I2C devices, enabling up to 8 AD7416 devices to be connected to a single bus.
  • Selectable Serial Bus Address: Enhances flexibility in system design by allowing multiple devices to share the same bus.
  • On-Chip Temperature Sensor: Provides accurate ambient temperature measurements with a working range of −40°C to +125°C.
  • Automatic Power-Down: Reduces power consumption by automatically entering power-down mode at the end of a conversion.
  • Wide Operating Supply Range: Operates from 2.7 V to 5.5 V, making it suitable for a variety of power supply environments.
  • OTI (Overtemperature Indicator) Pin: Provides an open-drain output that signals if the temperature exceeds a setpoint, useful for monitoring and control applications.

Applications

  • Data Acquisition with Ambient Temperature Monitoring: Ideal for systems that require precise temperature measurements alongside data acquisition.
  • Industrial Process Control: Suitable for monitoring temperatures in industrial environments.
  • Automotive Applications: Can be used in automotive systems for temperature monitoring and control.
  • Battery-Charging Applications: Useful for monitoring battery temperatures during charging cycles.
  • Personal Computers: Can be integrated into PC systems for temperature monitoring and thermal management.
