AD9788BSVZ

Digital To Analog Converters Overview

The AD9788BSVZ is a dual-channel, 16-bit digital-to-analog converter (DAC) from Analog Devices, operating at a maximum sample rate of 800 MSPS. It features low power 32-bit complex numerically controlled oscillators (NCOs) for carrier placement within the DAC bandwidth. The device includes internal digital upconversion, inverse sinc filtering, and programmable I/Q phase compensation. It utilizes a serial peripheral interface (SPI) for configuration and supports adjustable full-scale output currents ranging from 10 mA to 30 mA. The component operates on 1.8 V and 3.3 V supplies and is housed in a 100-lead TQFP package with an exposed pad.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'SVZ' against the manufacturer's current ordering guide to confirm package type and temperature range specifications. Ensure compatibility with the required 100-lead TQFP footprint and exposed pad thermal management requirements during procurement planning.

Digital To Analog Converters Selection Notes

Select the AD9788BSVZ when 16-bit resolution and 800 MSPS throughput are required for direct conversion transmit applications. Consider the integrated complex NCO and digital compensation features if minimizing external analog components for I/Q matching is a priority. Verify that the host system can support the necessary SPI interface and differential clock inputs.

Digital To Analog Converters Part Context

The AD9788 is part of the TxDAC family, which also includes the 12-bit AD9785 and 14-bit AD9787. These devices share pinouts and functional similarities but differ in resolution. The AD9788 provides the highest dynamic range within this specific group, suitable for demanding multicarrier generation applications up to the Nyquist frequency.

Digital To Analog Converters Replacement Considerations

The AD9785 and AD9787 are pin-compatible alternatives within the same datasheet. Selection depends on whether 12-bit or 14-bit resolution is sufficient for the application, as they offer identical form factors and feature sets aside from resolution differences.
