ADT7517ARQZ

Thermal Management Overview

The ADT7517ARQZ 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, 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 10-bit temperature sensor with four 10-bit DACs and a 10-bit 4-channel ADC in a single package.
• Features rail-to-rail buffered analog outputs for all DAC channels with simultaneous update capability via LDAC function.
• Supports multiple digital communication protocols including SPI, I2C, QSPI, and MICROWIRE through a flexible serial interface.
• Includes power-on reset logic ensuring DAC outputs initialize to 0 V and a low-power standby mode.

Thermal Management Applications

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

Thermal Management Procurement Notes

Verify the specific suffix ARQZ corresponds to the 16-lead QSOP package and industrial temperature grade when sourcing. Confirm that the required DAC resolution matches the 10-bit specification of the ADT7517 variant rather than the 12-bit or 8-bit alternatives within the same family. Ensure interface compatibility with the target system's microcontroller or processor bus standards.

Thermal Management Selection Notes

Select this component when a combined solution for thermal monitoring, analog input acquisition, and multi-channel voltage generation is required. The ADT7517 provides 10-bit DAC resolution, distinguishing it from the 12-bit ADT7516 and 8-bit ADT7519. Consider the DC input bandwidth and the 0 V to 2.28 V input range of the ADC channels for signal conditioning requirements. Evaluate the need for simultaneous DAC updates if precise timing between outputs is critical.

Thermal Management Part Context

The ADT7517 belongs to the ADT7516/ADT7517/ADT7519 family of mixed-signal devices. These parts share identical pinouts, packaging, and core functionality, differing primarily in DAC resolution. This family is designed for applications requiring integrated sensing and actuation capabilities within a compact form factor, leveraging Analog Devices' precision analog design techniques.

Thermal Management Replacement Considerations

Direct substitutes within the same package and functionality include the ADT7516ARQZ (12-bit DACs) and ADT7519ARQZ (8-bit DACs). Verify that the resolution difference aligns with application requirements before substitution.
