AD5516ABCZ-1

Digital To Analog Converters Overview

The AD5516ABCZ-1 is a 16-channel, 12-bit voltage-output digital-to-analog converter (DAC) housed in a 74-lead CSPBGA package. It features a fixed output voltage range of ±2.5 V and operates with supply voltages from 4.75 V to 15.75 V for analog rails and 2.7 V to 5.25 V for digital logic. The device utilizes a 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards, supporting clock rates up to 20 MHz. It offers 14-bit resolution via an Increment/Decrement Mode and includes asynchronous reset and power-down facilities.

• Industrial Control Systems

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'ABCZ-1' against the manufacturer's current ordering guide to confirm pinout compatibility and revision status. Ensure that the required ±2.5 V output span aligns with system requirements, as this variant differs from the ±5 V (AD5516-2) and ±10 V (AD5516-3) options. Confirm thermal management strategies are adequate for the 74-lead CSPBGA package given the junction temperature limits.

Digital To Analog Converters Selection Notes

Select the AD5516ABCZ-1 when a high-density solution requiring 16 independent voltage outputs is necessary. This model is appropriate for applications demanding a ±2.5 V output swing. Designers must provide a stable 3 V reference on the REF_IN pin. Consider the 25 ms typical calibration time in Mode 1 or the 1 ms update time in Mode 2 when determining system timing constraints.

Digital To Analog Converters Part Context

The AD5516 series comprises three variants differentiated by output voltage span: AD5516-1 (±2.5 V), AD5516-2 (±5 V), and AD5516-3 (±10 V). All share identical architecture, pinouts, and digital interfaces. The ABCZ-1 designation indicates the industrial temperature grade (-40°C to +85°C) and the specific ±2.5 V output configuration within the 74-lead CSPBGA form factor.

Digital To Analog Converters Replacement Considerations

Direct functional substitutes include AD5516ABCZ-2 for ±5 V output and AD5516ABCZ-3 for ±10 V output, provided the voltage span difference is acceptable. Other Analog Devices 16-channel DACs may require significant schematic redesign due to differing pinouts or interface protocols.
