AD9781BCPZRL

Digital To Analog Converters Overview

The AD9781BCPZRL is a dual-channel, 14-bit digital-to-analog converter (DAC) from Analog Devices. It supports sample rates up to 500 MSPS and features an LVDS interface with dual-port or interleaved single-port operation. The device includes internal gain and offset compensation for direct conversion transmit applications. Key electrical parameters include a maximum power dissipation of 315 mW at full scale, differential analog current outputs programmable from 8.6 mA to 31.7 mA, and an internal 1.2 V precision reference. It operates on 1.8 V and 3.3 V supplies and is housed in a 72-lead LFCSP package.

Digital To Analog Converters Feature Summary

• Dual 14-bit DACs with 500 MSPS sampling rate
• LVDS data inputs supporting dual-port or interleaved modes
• Internal 1.2 V reference and auxiliary 10-bit current DACs for offset nulling
• Programmable full-scale output current (8.6 mA to 31.7 mA)
• Low noise and intermodulation distortion performance

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and reel specifications. Ensure compatibility with the required thermal management solutions for the 72-lead LFCSP package during integration.

Digital To Analog Converters Selection Notes

Select this component when high dynamic range and low IMD are required for multi-carrier transmission systems. Compare resolution and speed requirements against the pin-compatible AD9780 (12-bit) and AD9783 (16-bit) variants if system constraints differ.

Digital To Analog Converters Part Context

This part belongs to the AD9780/AD9781/AD9783 family of high-performance DACs. These devices share a common pinout and functional architecture, differing primarily in resolution (12, 14, and 16 bits respectively). They are designed for direct conversion transmitter architectures.

Digital To Analog Converters Replacement Considerations

Pin-compatible alternatives within the same family include the AD9780BBCPZRL (12-bit) and AD9783BBCPZRL (16-bit). Verify that the resolution change meets application requirements before substitution.
