ADT7517ARQZ-REEL7

Thermal Management Overview

The ADT7517ARQZ-REEL7 is a mixed-signal integrated circuit combining a 10-bit temperature-to-digital converter, a 10-bit four-channel analog-to-digital converter, and four 10-bit digital-to-analog converters. It operates on a single supply voltage ranging from 2.7 V to 5.5 V. The device features an internal bandgap temperature sensor with typical accuracy of ±0.5°C and supports both SPI and I2C serial interfaces. It includes a power-down mode consuming less than 10 μA and provides buffered voltage outputs.

Thermal Management Feature Summary

• Integrates a 10-bit temperature sensor, four-channel ADC, and quad DAC in a single package
• Supports dual serial communication protocols including SPI and SMBus/I2C compatibility
• Features rail-to-rail output buffers for all DAC channels with simultaneous update capability
• Incorporates a low-power standby mode controlled via the serial interface

Thermal Management Applications

• Portable battery-powered instruments
• Personal computers
• Smart battery chargers
• Telecommunications systems
• Process control

Thermal Management Procurement Notes

Verify the specific revision level (Rev. B) against the manufacturer's datasheet to ensure compatibility with system requirements. Confirm that the QSOP-16 package dimensions match the PCB footprint design. Ensure the ordering suffix corresponds to the required reel quantity and packaging format for automated assembly processes.

Thermal Management Selection Notes

Select this component when a combined solution for thermal monitoring, analog input acquisition, and voltage generation is required. The ADT7517 offers 10-bit resolution for both ADC and DAC functions, suitable for applications needing moderate precision. Consider the operating temperature range of −40°C to +120°C for industrial environments.

Thermal Management Part Context

This part belongs to the ADT7516/ADT7517/ADT7519 family from Analog Devices. While functionally similar, the ADT7517 is distinguished by its 10-bit DAC resolution, whereas the ADT7516 provides 12-bit resolution and the ADT7519 provides 8-bit resolution. All variants share the same pinout and core functionality.

Thermal Management Replacement Considerations

Direct substitutes within the same family include the ADT7516ARQZ-REEL7 and ADT7519ARQZ-REEL7. These parts share identical pin configurations and software registers but differ in DAC resolution. Verify that the specific resolution requirements of the application are met by the replacement part.
