AD9777BSVZRL

Digital To Analog Converters Overview

The AD9777BSVZRL is a 16-bit, dual-channel digital-to-analog converter (DAC) from Analog Devices. It supports input and output data rates up to 400 MSPS with selectable 2×, 4×, or 8× interpolation filters. The device operates on a single 3.1 V to 3.5 V supply, consuming approximately 1.2 W of power at full scale. Key features include programmable channel gain and offset adjustment, fS/2, fS/4, and fS/8 digital quadrature modulation capabilities, and an internal PLL clock multiplier. It utilizes an 80-lead thin quad flat package with an exposed pad (TQFP_EP).

Digital To Analog Converters Feature Summary

• 16-bit resolution with maximum DAC update rate of 400 MSPS.
• Selectable 2×, 4×, or 8× interpolating half-band filters.
• Programmable channel gain control (±1 dB range) and offset adjustment (±10% FSR).
• Internal 1.2 V bandgap voltage reference and PLL clock multiplier.

Digital To Analog Converters Applications

• Wideband CDMA and multicarrier GSM systems.
• Multicarrier TDMA and CDMA transmitters.
• High-order QAM modulation schemes.
• Direct IF transmission for frequencies above 70 MHz.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'BSVZRL' against the manufacturer's current ordering guide to confirm package type, temperature grade, and reel packaging specifications. Ensure compatibility with standard SPI programming interfaces and check for any recent pinout revisions in the latest datasheet revision.

Digital To Analog Converters Selection Notes

Select this component for applications requiring high linearity and flexible digital filtering. Consider the 1.2 W power dissipation and thermal requirements for the TQFP_EP package. Verify that the system clock interface supports the required differential or single-ended inputs and that the 3.3 V logic levels are compatible with the host processor.

Digital To Analog Converters Part Context

The AD9777 is part of the AD977x family of pin-compatible, high-performance interpolating DACs. It shares architectural similarities with other members like the AD9773 and AD9778 but offers unique 16-bit resolution and advanced digital modulation features tailored for complex transmit signal chains.

Digital To Analog Converters Replacement Considerations

Check the official AD977x ordering guide for pin-compatible alternatives within the same family. Ensure any substitute maintains the 16-bit resolution, 400 MSPS speed, and TQFP_EP package dimensions if board space is constrained.
