AD5516ABC-2

Digital To Analog Converters Overview

The AD5516ABC-2 is a 16-channel, 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features a 3-wire serial interface compatible with SPI and DSP standards, operating at clock rates up to 20 MHz. The device provides an output voltage range of ±5 V and includes an Increment/Decrement Mode for 14-bit resolution fine adjustment. Packaged in a 74-lead CSPBGA (12 mm × 12 mm), it operates with AVCC = 5 V, DVCC = 2.7 V to 5.25 V, and dual supplies VDD/VSS ranging from ±4.75 V to ±15.75 V. A stable 3 V reference on REF_IN is required.

Digital To Analog Converters Feature Summary

• 16 integrated 12-bit DAC channels in a single 74-lead CSPBGA package
• Increment/Decrement Mode enables 14-bit monotonic resolution via 0.25 LSB steps
• 3-wire serial interface supports SPI, QSPI, MICROWIRE, and DSP protocols
• Fixed ±5 V output voltage range with 0.5 Ω DC output impedance

Digital To Analog Converters Applications

• Automatic Test Equipment
• Industrial Control Systems
• Data Acquisition
• Optical Networks
• Level Setting Instrumentation

Digital To Analog Converters Procurement Notes

Verify the specific suffix ABC-2 confirms the ±5 V output span before procurement. Ensure the design accommodates the 74-lead CSPBGA package thermal requirements and reflow soldering profiles. Confirm that the system power supplies meet the specified ranges for AVCC, DVCC, VDD, and VSS to maintain guaranteed performance specifications.

Digital To Analog Converters Selection Notes

Select the AD5516ABC-2 when a ±5 V output range is required; choose ABC-1 for ±2.5 V or ABC-3 for ±10 V spans. Consider the Increment/Decrement Mode if 14-bit precision is necessary, noting that update rates differ between Mode 1 and Mode 2. Ensure the application can provide a low-noise 3 V reference on the REF_IN pin to achieve optimal linearity and accuracy.

Digital To Analog Converters Part Context

The AD5516 series integrates sixteen 12-bit DACs into a high-density package, reducing board space compared to discrete solutions. The ABC-2 variant specifically targets applications requiring a ±5 V swing. The device utilizes a self-calibrating architecture to maintain 12-bit performance, with the BUSY pin indicating calibration status. It is part of a broader family including evaluation boards like EVAL-AD5516-2EBZ for development purposes.
