Overview

Description

ADT7490ARQZ is an Analog Devices digital temperature sensor IC. It provides real‑time temperature readings to a host MCU over I2C. The -ARQZ suffix indicates a specific RoHS‑qualified packaging option (tape-and-reel).
Key points:
- Digital temperature sensing with I2C interface
- Programmable resolution/update rate and optional alert/interrupt outputs
- Suitable for multi-point or single‑point temperature monitoring in embedded systems, GPUs/CPUs, power electronics, and data‑center gear
- Includes low‑power modes and flexible configuration
Basic usage:
- Power the device per datasheet, connect SCL/SDA with pull‑ups, and share a common ground
- Use the I2C address to read the temperature data from the temperature register
- Configure via control registers (resolution, update rate, shutdown, alerts) as needed
For exact specifications, pinout, register map, and timing, refer to the ADT7490ARQZ datasheet.

Features

ADT7490ARQZ features (typical):
- I2C (2-wire) digital temperature sensor
- 10-bit temperature data output
- Temperature range: -40°C to +125°C
- Supply voltage: 2.7 V to 5.5 V
- Low power operation with selectable modes (continuous/one-shot)
- Fast conversion time
- Optional Alert/Interrupt output
- Pb-free, RoHS-compliant 8-pin package (ARQZ)
Note: Refer to the datasheet for exact accuracy, timing, and pin details.

Package

ADT7490ARQZ is in a leadless LFCSP package, 20 leads (4x4 mm).

Pinout

- Pin count: 28 pins (package ARQZ).
- Function: 8-channel digital temperature sensor/monitor with I2C/SMBus interface; reads temperatures from up to 8 inputs, exposes data via registers, and provides alert/status outputs.

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI).
- Company type: An American multinational semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits, including sensors like temperature sensors.

Application

Applications:
- Multi-point thermal monitoring on complex boards (servers, desktops, embedded systems)
- VRM/PMIC and MOSFET temperature sensing for power supplies and cooling control
- Industrial and telecom equipment hot-spot detection
- Data-center environmental monitoring and fan-speed control
- Motor drives and medical devices requiring accurate temperature readings

Equivalent

Direct cross-reference for ADT7490ARQZ doesn’t exist. Closest equivalents are:
- Analog Devices: ADT7420, ADT7422 (I2C temperature monitors in the same family)
- Other vendors: TI TMP75/TMP102, NXP LM75/LM75A (functionally similar I2C temperature sensors)
Note: pinout, resolution, and I2C protocol may differ; verify specs and package compatibility before substituting.
