AD9783BCPZRL

Digital To Analog Converters Overview

The AD9783BCPZRL is a dual-channel, 16-bit digital-to-analog converter (DAC) from Analog Devices Inc., operating at sample rates up to 500 MSPS. It features low noise and intermodulation distortion, with a single carrier W-CDMA ACLR of -82 dBc at 61.44 MHz IF. The device utilizes an LVDS interface for data input and includes proprietary switching output stages that allow usable analog outputs beyond the Nyquist frequency. Key specifications include a full-scale output current programmable from 8.6 mA to 31.7 mA, auxiliary 10-bit current DACs for offset nulling, and an internal 1.2 V precision reference. Power consumption is 315 mW at maximum sample rate.

Digital To Analog Converters Feature Summary

• Dual 16-bit DACs with 500 MSPS sampling rate
• LVDS interface supporting dual-port or interleaved single-port operation
• Proprietary switching output stage enabling synthesis above Nyquist frequency
• Programmable full-scale current (8.6 mA to 31.7 mA) and auxiliary offset DACs

Digital To Analog Converters Applications

• Wireless infrastructure including W-CDMA, CDMA2000, TD-SCDMA, and WiMAX
• Wideband communications such as LMDS/MMDS and point-to-point links
• RF signal generators and arbitrary waveform generators

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix RL indicates tape and reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure supply chain sources provide valid traceability for the Analog Devices Inc. component.

Digital To Analog Converters Selection Notes

Select the AD9783BCPZRL when 16-bit resolution and high dynamic range are required for direct conversion transmit applications. Verify compatibility with LVDS data interfaces and ensure system power supplies support the specified 1.8 V and 3.3 V rails. Consider the 72-lead LFCSP package footprint for PCB layout constraints.

Digital To Analog Converters Part Context

This component belongs to the AD9780/AD9781/AD9783 family of pin-compatible, high dynamic range dual DACs. The AD9783 variant specifically provides 16-bit resolution, distinguishing it from the 12-bit AD9780 and 14-bit AD9781 models within the same series.

Digital To Analog Converters Replacement Considerations

Pin-compatible alternatives within the same family include the AD9780 (12-bit) and AD9781 (14-bit). These variants share identical pinouts and functionality but offer lower resolution.
