AD9775BSVZRL

Digital To Analog Converters Overview

The AD9775BSVZRL is a 14-bit, dual-channel digital-to-analog converter from Analog Devices. It supports input data rates up to 160 MSPS and output update rates up to 400 MSPS. The device integrates selectable 2×, 4×, or 8× interpolating filters and programmable channel gain/offset controls. It features an internal PLL clock multiplier, fS/2, fS/4, and fS/8 digital quadrature modulation capabilities, and direct IF transmission mode. Operating on a single 3.1 V to 3.5 V supply, it typically dissipates 1.2 W of power. The component is housed in an 80-lead thin quad flat package with an exposed pad (TQFP_EP).

Digital To Analog Converters Feature Summary

• 14-bit resolution with 400 MSPS maximum DAC output update rate.
• Selectable 2×, 4×, or 8× interpolating half-band filters.
• Integrated SPI port for programmable gain, offset, and modulation control.
• Supports fS/2, fS/4, and fS/8 digital quadrature modulation with image rejection.

Digital To Analog Converters Applications

• Analog quadrature modulation architectures.
• 3G, multicarrier GSM, TDMA, and CDMA systems.
• Broadband wireless and point-to-point microwave radios.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'BSVZRL' against the manufacturer's current ordering guide to confirm package type and reel specifications. Ensure compatibility with the required interpolation filter settings and clock interface configurations during system design validation.

Digital To Analog Converters Selection Notes

Select this component for applications requiring high linearity and flexible digital modulation. Consider the 1.2 W typical power dissipation and the need for thermal management due to the TQFP_EP package. Verify that the system clock interface supports the required differential or single-ended inputs for the internal PLL.

Digital To Analog Converters Part Context

The AD9775 is part of the AD977x family of pin-compatible, high-performance interpolating TxDAC+ converters. This family shares common architectural features, including the serial port interface and interpolation filter options, allowing for scalable design across different resolution and speed requirements within the same product line.

Digital To Analog Converters Replacement Considerations

The AD9775BSVZ is the non-reel variant of this component. Other members of the AD977x family may offer pin compatibility but differ in resolution or performance metrics.
