AD9787BSVZRL

Digital To Analog Converters Overview

The AD9787BSVZRL is a dual-channel, 14-bit, high dynamic range TxDAC device manufactured by Analog Devices Inc. It supports a maximum sample rate of 800 MSPS and operates from 3.3 V analog/digital supplies and 1.8 V clock/digital supplies. The component features low power 32-bit complex numerically controlled oscillators (NCOs) for carrier placement within the DAC bandwidth. Key specifications include a typical spurious-free dynamic range (SFDR) of 87 dBc at 800 MSPS with 8× interpolation, and a full-scale output current adjustable between 8.66 mA and 31.66 mA. It is housed in a 100-lead exposed pad TQFP package.

Digital To Analog Converters Feature Summary

• Dual 14-bit DAC architecture with 800 MSPS maximum sampling rate
• Integrated low power 32-bit complex NCO for digital upconversion
• Auxiliary DACs for I/Q gain matching and offset control
• Internal digital inverse sinc filter and programmable phase compensation

Digital To Analog Converters Applications

• Wireless infrastructure base stations
• W-CDMA, CDMA2000, TD-SCDMA, WiMAX, and GSM systems
• Digital high or low IF synthesis
• Transmit diversity applications

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 that the supply voltage requirements (AVDD33/DVDD33 at 3.3 V and CVDD18/DVDD18 at 1.8 V) are compatible with the target system design before procurement.

Digital To Analog Converters Selection Notes

Select the AD9787BSVZRL when a 14-bit resolution is required for dual-channel applications operating up to 800 MSPS. Consider the internal complex NCO and auxiliary DACs if direct conversion transmit architectures with I/Q correction are needed. Verify thermal management capabilities as the device dissipates approximately 450 mW in standard modes.

Digital To Analog Converters Part Context

The AD9787BSVZRL belongs to the AD9785/AD9787/AD9788 family of TxDAC devices. The primary distinction within this family is the resolution: the AD9785 offers 12 bits, the AD9787 provides 14 bits, and the AD9788 delivers 16 bits. All variants share the same 800 MSPS sample rate, pinout, and functional block diagram.

Digital To Analog Converters Replacement Considerations

The AD9785BSVZRL and AD9788BSVZRL are functionally compatible alternatives within the same family, differing only in resolution (12-bit and 16-bit, respectively). Other series such as the AD977x or AD9780 utilize different interfaces or sample rates and are not direct pin-compatible replacements.
