AD9786BSV

Digital To Analog Converters Overview

The AD9786BSV is a 16-bit, high-speed CMOS digital-to-analog converter (DAC) featuring 2×/4×/8× interpolation and signal processing capabilities. It supports a maximum DAC update rate of 500 MSPS with an input data rate up to 200 MSPS. The device includes selectable modulation modes (fDAC/2, fDAC/4, fDAC/8), image rejection Hilbert transform, and flexible calibration. It operates from a 3.1 V to 3.5 V analog supply (AVDD), 2.5 V digital supply (DVDD), and 3.3 V driver supply (DRVDD). Key specifications include ±0.6 LSB INL, ±0.3 LSB DNL, and a nominal full-scale output current of 20 mA in an 80-lead TQFP_EP package.

Digital To Analog Converters Procurement Notes

Verify the suffix 'BSV' against the manufacturer's official ordering guide to confirm specific packaging, temperature range, or lead finish variations. Ensure compatibility with the required 80-lead TQFP_EP thermally enhanced package dimensions and thermal pad soldering requirements specified in the datasheet outline.

Digital To Analog Converters Selection Notes

Select this component when 16-bit linearity and high-speed interpolation are required for complex modulated signals. Consider the internal 1.2 V reference if external precision references are not available. Verify that the system clock supports the required LVPECL, CMOS, or sine wave inputs and that the power supply rails (3.3 V AVDD, 2.5 V DVDD) align with the design constraints.

Digital To Analog Converters Part Context

The AD9786 belongs to Analog Devices' TxDAC+ family of high-performance digital-to-analog converters. This series is engineered for demanding communications applications requiring low noise and high spurious-free dynamic range. The BS variant typically denotes a specific commercial grade or packaging option within the broader AD9786 product line.

Digital To Analog Converters Replacement Considerations

Consult the official Analog Devices replacement matrix for verified cross-references. Ensure any substitute maintains 16-bit resolution, comparable interpolation factors, and compatible pinout for the 80-lead TQFP_EP package.
