Product Overview
The AD9775BSVZ is a dual-channel 14-bit high-speed DAC from Analog Devices TxDAC+ series. Designed for communication infrastructure, radar and test instruments, it supports up to 160 MSPS input sampling rate and reaches 400 MSPS via built-in 2×/4×/8× programmable interpolation filters. Equipped with integrated digital complex modulator and PLL clock multiplier, it realizes direct IF synthesis with consistent phase between two channels. Packaged in 80-lead TQFP-EP with exposed thermal pad, it serves as a stable signal generation chip for high-dynamic-range transmitters.
Core Advantages
Advanced Programmable Interpolation Filters
2×/4×/8× configurable hardware filters suppress out-of-band noise, reduce FPGA load and simplify external analog circuits.
Integrated Complex Digital Modulation
Built-in digital modulator supports single-sideband up-conversion, enabling direct IF output and eliminating analog quadrature imbalance.
Excellent SFDR Performance
Segmented current-source architecture delivers high spurious-free dynamic range for clean spectrum in multi-carrier communication systems.
Dual Matched High-Speed DAC Channels
Two well-matched 14-bit DAC cores offer high channel isolation and consistent phase for standard I/Q transmission designs.

Frequently Asked Questions
Q1: Are AD9775BSVZ chips 100% original new?
A1: All ICs are brand new factory-original from ADI. Strict ESD & appearance inspection, shipped with original moisture-proof trays.
Q2: Why is the exposed EP pad necessary for this chip?
A2: The chip runs up to 400 MSPS and generates heat. The exposed pad provides low thermal resistance, stable performance and longer service life when soldered to PCB copper area.
Q3: How do internal interpolation filters ease FPGA load?
A3: Input data can be transmitted at low rates, while the chip internally up-samples to 400 MSPS. It cuts FPGA power consumption and simplifies peripheral filter circuits.
Q4: Can I get timing diagrams and bulk discount?
A4: Fill in our inquiry form with your project parameters and order quantity. Our engineering team will send official docs and customized quotation within one day.
Q5: What’s the lead time for AD9775BSVZ?
A5: In-stock items ship within 1-2 working days; out-of-stock orders take 2-4 weeks delivery.
Q6: Can I order small samples for testing?
A6: Yes, MOQ is 1 piece. Sample orders are supported for laboratory and prototype verification.
Q7: Do you offer after-sales replacement for defective parts?
A7: We provide 1-year warranty. Defective goods caused by manufacturing will be replaced free of charge.
Q8: Is technical consultation free during my project design?
A8: Our engineer team offers free technical support for circuit matching and parameter configuration of AD9775BSVZ.
