AD9144BCPZ

Overview

The AD9144BCPZ is a quad, 16-bit digital-to-analog converter (DAC) from Analog Devices Inc., housed in an 88-lead LFCSP package. It supports a maximum sample rate of 2.8 GSPS with selectable 1×, 2×, 4×, or 8× interpolation filters. The device features an 8-lane JESD204B interface and a high-performance PLL clock multiplier. Key electrical parameters include a typical SFDR of 82 dBc at DC IF and −9 dBFS, DNL of ±1.0 LSB, and INL of ±2.0 LSB. Full-scale output current is programmable between 13.9 mA and 27.0 mA. Power consumption is 1.6 W at 1.6 GSPS and 1.7 W at 2.0 GSPS under full operating conditions.

Feature Summary

• Quad 16-bit DAC architecture supporting up to 2.8 GSPS sampling rate
• Flexible 8-lane JESD204B interface with Subclass 1 support for deterministic latency
• Integrated low-noise PLL clock multiplier and digital inverse sinc filter
• Programmable transmit enable function for power optimization

Applications

• Wireless communications including 3G/4G W-CDMA base stations
• Software defined radios and wideband repeaters
• Automated test equipment and instrumentation
• Point-to-point and LMDS/MMDS systems

Procurement Notes

Verify the specific suffix 'BCPZ' against the manufacturer's ordering guide to confirm package type and temperature range. Confirm RoHS compliance status through official documentation. Ensure supply voltage requirements match system design constraints before procurement.

Selection Notes

Select this component for applications requiring high dynamic range and ultrawide complex signal bandwidth exceeding 1 GHz. Consider the 88-lead LFCSP footprint and thermal resistance characteristics for PCB layout. Verify compatibility with downstream analog quadrature modulators if direct interfacing is planned.
