AD9781BCPZ Description

Short technical summary and product information.

The AD9781BCPZ is a dual 14-bit digital-to-analog converter (DAC) from Analog Devices, part of the AD9780/AD9781/AD9783 family. It features LVDS parallel data interface and supports sample rates up to 500 MSPS, making it suitable for high-speed direct conversion transmit applications.

 

The DAC provides differential current outputs with quad-switch architecture for low distortion. Key electrical specifications include INL of ±1 LSB and DNL of ±0.5 LSB. The device operates from separate digital (1.7V to 1.9V) and analog (3.13V to 3.47V) supply rails, and includes an internal 1.2V precision reference. Power dissipation is 315 mW.

 

The AD9781BCPZ is packaged in a 72-lead LFCSP (10x10 mm) with exposed pad for thermal management. It supports surface mount assembly and operates over -40°C to 85°C. The device is RoHS3 compliant.

 

Target applications include wireless infrastructure (W-CDMA, CDMA2000, TD-SCDMA, WiMAX), wideband communications (LMDS, MMDS, point-to-point), and RF signal generation.
