AD9144BCPAZ

Overview

The AD9144BCPAZ is a quad, 16-bit digital-to-analog converter (DAC) from Analog Devices Inc., featuring the TxDAC+ architecture. It supports a maximum sample rate of 2.8 GSPS with selectable 1×, 2×, 4×, or 8× interpolation filters. The device integrates an 8-lane JESD204B interface and a high-performance PLL clock multiplier. Key electrical specifications include ±1.0 LSB DNL and ±2.0 LSB INL accuracy. Power consumption is rated at 1.6 W at 1.6 GSPS and 1.7 W at 2.0 GSPS under full operating conditions. It operates within a temperature range of -40°C to +85°C.

Feature Summary

• Quad-channel 16-bit resolution with up to 2.8 GSPS update rate
• Flexible 8-lane JESD204B interface supporting Subclass 1 synchronization
• Integrated low-noise PLL clock multiplier for deterministic latency
• Programmable transmit enable function for power optimization

Applications

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

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status via official documentation. Ensure proper ESD handling procedures are followed during storage and installation due to the sensitivity of the CMOS inputs and internal circuitry.

Selection Notes

Select this model for applications requiring high dynamic range and wide complex signal bandwidth exceeding 1 GHz. Consider the 88-lead LFCSP package constraints and thermal management requirements, as the exposed pad must be soldered to the ground plane for optimal heat dissipation and mechanical stability.

Part Context

This component belongs to the AD9144 series of high-speed DACs. It is designed to interface seamlessly with analog quadrature modulators such as the ADRF6720. The BCPZ suffix indicates specific packaging and environmental compliance variations within the standard AD9144 product line.

Replacement Considerations

Direct functional replacements within the same family include the AD9144BCPZ and AD9144ACPZ variants. These share identical pinouts and core specifications but may differ in manufacturing lot or specific environmental certifications.
