AD9787BSVZ

Digital To Analog Converters Overview

The AD9787BSVZ is a dual-channel, 14-bit, high dynamic range TxDAC device manufactured by Analog Devices Inc. It operates at a maximum sample rate of 800 MSPS and supports multicarrier generation up to the Nyquist frequency. The component features a low-power 32-bit complex numerically controlled oscillator (NCO) that adds less than 300 mW to power consumption. Key specifications include a differential nonlinearity (DNL) of ±0.5 LSB and an integral nonlinearity (INL) of ±1.0 LSB. It utilizes a CMOS data input interface with adjustable setup and hold times and operates from 1.8 V and 3.3 V supplies within a -40°C to +85°C temperature range.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure package and tape-and-reel configurations match design requirements. Confirm RoHS compliance status and moisture sensitivity levels prior to procurement. Cross-reference the part number with official distributor catalogs to validate availability and lead times.

Digital To Analog Converters Selection Notes

Select the AD9787BSVZ when a 14-bit resolution is required for dual-channel applications operating up to 800 MSPS. Ensure the system design accommodates the 100-lead TQFP package dimensions and thermal dissipation needs. Verify that the host processor can support the parallel data interface and SPI programming requirements defined in the datasheet.

Digital To Analog Converters Part Context

The AD9787BSVZ belongs to the AD9785/AD9787/AD9788 family of TxDAC devices. While sharing the same package and core architecture, it is distinguished by its 14-bit resolution, whereas the AD9785 offers 12 bits and the AD9788 provides 16 bits. All variants share identical pinouts and supply voltage requirements.

Digital To Analog Converters Replacement Considerations

The AD9785BSVZ and AD9788BSVZ are pin-compatible members of the same family but differ in resolution. No other direct cross-model replacements are documented in the provided source material.
