ADT7517ARQZ-REEL

Thermal Management Overview

The ADT7517ARQZ-REEL is a board-mount temperature sensor IC from Analog Devices, housed in a 16-lead QSOP package. It integrates a 10-bit temperature-to-digital converter, a 10-bit 4-channel ADC with DC input bandwidth, and four 10-bit buffered voltage output DACs. The device operates on a single supply ranging from 2.7 V to 5.5 V. It supports SPI, I2C, QSPI, MICROWIRE, and DSP compatible serial interfaces. The internal temperature sensor offers typical accuracy of ±0.5°C over the operating range of −40°C to +120°C.

Thermal Management Feature Summary

• Integrates a quad 10-bit digital-to-analog converter with rail-to-rail buffered outputs and simultaneous update capability via LDAC function.
• Includes a 10-bit analog-to-digital converter supporting four single-ended channels with selectable input ranges.
• Features an on-chip band gap temperature sensor for local thermal monitoring with high resolution.
• Provides flexible communication through dual-mode serial interfaces compatible with standard bus protocols.

Thermal Management Applications

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

Thermal Management Procurement Notes

Verify the specific ordering suffix REEL against manufacturer documentation to confirm tape-and-reel packaging configuration. Ensure the component meets RoHS compliance requirements for your assembly process. Confirm availability status as distribution channels may report limited stock or end-of-life conditions for this specific variant.

Thermal Management Selection Notes

Select this component when a combined solution for thermal sensing, analog input acquisition, and multi-channel voltage generation is required. The 10-bit DAC resolution suits applications needing moderate precision control. Verify that the 2.7 V to 5.5 V supply range aligns with the system power architecture and that the QSOP package fits the PCB layout constraints.

Thermal Management Part Context

This part belongs to the ADT7516/ADT7517/ADT7519 family, differentiated primarily by DAC resolution. The ADT7517 specifically provides four 10-bit DACs, whereas the ADT7516 offers 12-bit and the ADT7519 offers 8-bit resolutions. All variants share identical pinouts, interface capabilities, and sensor specifications within the QSOP package.

Thermal Management Replacement Considerations

Public confirmed substitutes include ADT7516ARQZ-REEL and ADT7519ARQZ-REEL. These parts share the same package and interface but differ in DAC bit depth. No other direct functional equivalents are documented in the provided source material.
