AD9144BCPZRL

Overview

The AD9144BCPZRL is a quad, 16-bit digital-to-analog converter (DAC) from Analog Devices Inc., featuring a maximum sample rate of 2.8 GSPS. It utilizes an 8-lane JESD204B interface and supports selectable 1×, 2×, 4×, or 8× interpolation filters. The device operates with analog supply voltages of 3.3 V and digital supplies of 1.2 V. Key performance metrics include an SFDR of 82 dBc at DC IF and a full-scale output current range of 13.9 mA to 27.0 mA. It is housed in an 88-lead LFCSP package.

Feature Summary

• Quad-channel architecture with 16-bit resolution and 2.8 GSPS maximum update rate
• Flexible 8-lane JESD204B serial interface supporting Subclass 1 synchronization
• Integrated high-performance PLL clock multiplier and digital inverse sinc filter
• Programmable transmit enable function for power optimization

Applications

• Wireless communications base stations
• Software defined radios
• Wideband repeaters
• Automated test equipment

Procurement Notes

Verify the RL suffix indicates reel packaging by consulting the manufacturer's official ordering guide. Confirm RoHS compliance status through the specific product datasheet revision. Ensure compatibility with standard JESD204B host interfaces during system integration planning.

Selection Notes

Select this component for applications requiring ultrawide complex signal bandwidth exceeding 1 GHz. Evaluate power consumption requirements against the specified 1.6 W at 1.6 GSPS. Ensure the design accommodates the 88-lead LFCSP footprint and thermal dissipation needs via the exposed pad.

Part Context

This part belongs to the AD9144 family of TxDAC+ converters. It shares architectural similarities with other high-speed DACs in the series but is distinguished by its specific 2.8 GSPS capability and quad-channel configuration optimized for direct RF synthesis.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult the manufacturer's ordering guide for potential pin-compatible alternatives within the same product family.
