ADT7516ARQZ

Thermal Management Overview

The ADT7516ARQZ is a board-mount temperature sensor IC in a 16-lead QSOP package. It integrates a 10-bit temperature-to-digital converter, a 10-bit 4-channel ADC, and four 12-bit DACs with buffered voltage outputs. The device operates on a single supply from 2.7 V to 5.5 V. It supports SPI, I2C, QSPI, MICROWIRE, and DSP interfaces. The internal temperature sensor accuracy is ±0.5°C typical at 3.3 V. The ADC input range is 0 V to 2.28 V or 0 V to VDD. The DAC output range is 0 V to VREF.

Thermal Management Feature Summary

• Integrates four 12-bit digital-to-analog converters with rail-to-rail buffered outputs.
• Includes a 10-bit analog-to-digital converter for monitoring multiple analog channels.
• Features an on-chip band gap temperature sensor with high resolution.
• Supports dual serial interface modes including SMBus/I2C and 4-wire SPI.

Thermal Management Applications

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

Thermal Management Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your assembly process. Confirm availability status as distribution channels may vary. Cross-reference the pinout with your PCB footprint design to ensure compatibility.

Thermal Management Selection Notes

Select this component when a combined solution for temperature monitoring, analog signal acquisition, and multi-channel voltage generation is required. The integrated nature reduces board space compared to discrete components. Consider the supply voltage range and interface compatibility with the host microcontroller. Evaluate the need for simultaneous DAC updates via the LDAC function.

Thermal Management Part Context

This part belongs to the ADT7516/ADT7517/ADT7519 family from Analog Devices. The family shares a common architecture but differs in DAC resolution. The ADT7516 specifically provides 12-bit DAC resolution, whereas the ADT7517 offers 10-bit and the ADT7519 offers 8-bit resolution. All variants share the same 16-lead QSOP package and peripheral features.
