AD9786BSVZRL

Digital To Analog Converters Overview

The AD9786BSVZRL is a 16-bit, high-speed CMOS digital-to-analog converter (DAC) featuring 2×/4×/8× interpolation and signal processing. It supports a maximum DAC output update rate of 500 MSPS with a nominal full-scale current of 20 mA. The device includes selectable modulation modes (fDAC/2, fDAC/4, fDAC/8), a flexible calibration engine, and an on-chip 1.2 V reference. It operates from a 3.1 V to 3.5 V analog supply (AVDD) and a 2.5 V digital supply (DVDD). Key dynamic specifications include an SFDR of up to 93 dBc and an IMD of 90 dBc at 10 MHz. The component is housed in an 80-lead thermally enhanced TQFP_EP package.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'RL' against the manufacturer's official ordering guide to confirm reel packaging and any associated handling requirements. Ensure compatibility with the required 80-lead TQFP_EP footprint during procurement planning. Cross-reference the revision history to confirm the component corresponds to Rev. B specifications.

Digital To Analog Converters Selection Notes

Select this component when a 16-bit resolution with up to 500 MSPS output rate is required. It is suitable for applications needing integrated interpolation filters to reduce external clock complexity. Consider the power supply requirements: 3.1–3.5 V for analog/digital I/O and 2.5 V for internal logic and clock domains. Verify that the 80-lead TQFP_EP package fits the thermal and spatial constraints of the design.

Digital To Analog Converters Part Context

The AD9786 belongs to Analog Devices' TxDAC+® family of high-speed DACs. It is designed for demanding communications applications requiring state-of-the-art distortion and noise performance. The device integrates multiple functions typically found in separate components, such as interpolation filtering and signal processing, to simplify system architecture.

Digital To Analog Converters Replacement Considerations

Consult the manufacturer's datasheet for the complete list of compatible pin-to-pin or functionally equivalent parts within the AD9786 series. Verify that any substitute maintains the same 16-bit resolution, 500 MSPS update rate, and 80-lead TQFP_EP package dimensions.
