AD9773BSV

Digital To Analog Converters Overview

The AD9773BSV is a 12-bit, dual-channel digital-to-analog converter (DAC) from Analog Devices, operating at a maximum DAC update rate of 400 MSPS. It features selectable 2×, 4×, or 8× interpolating filters and supports fS/2, fS/4, and fS/8 digital quadrature modulation with image rejection. The device includes an internal PLL clock multiplier, programmable channel gain and offset adjustment, and a fully compatible SPI interface. It operates on a single 3.1 V to 3.5 V supply, consuming approximately 1.2 W of power, and is housed in an 80-lead thin quad flat package with an exposed pad (TQFP_EP).

Digital To Analog Converters Feature Summary

• 12-bit resolution with 400 MSPS maximum output data rate.
• Selectable 2×, 4×, or 8× interpolation filters for simplified reconstruction filtering.
• Digital quadrature modulation capability (fS/2, fS/4, fS/8) with image rejection architecture.
• Internal 1.2 V reference and programmable PLL clock multiplier.

Digital To Analog Converters Applications

• Analog quadrature modulation architectures.
• 3G, multicarrier GSM, TDMA, and CDMA systems.
• Broadband wireless and point-to-point microwave radios.
• Instrumentation and automatic test equipment (ATE).

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'BSV' against the manufacturer's current ordering guide to confirm package type, temperature range, and reel specifications. Ensure compatibility with the required thermal management solutions for the TQFP_EP package, as junction temperature limits apply.

Digital To Analog Converters Selection Notes

Select this component for applications requiring high dynamic range and flexible digital upconversion. Consider the 1.2 W power dissipation and the need for a 3.3 V single supply. Verify that the input data interface supports the required straight binary or two's complement formats and that the system can accommodate the parallel data inputs.

Digital To Analog Converters Part Context

The AD9773 is part of the AD977x family of pin-compatible, high-performance, programmable interpolating TxDAC+ converters. This family shares common architectural features, including the serial port interface and interpolation filter options, allowing for design flexibility across different resolution and speed requirements within the same product line.

Digital To Analog Converters Replacement Considerations

Consult the official datasheet ordering guide for confirmed pin-compatible alternatives within the AD977x family. No external substitute part numbers are verified in the provided documentation.
