AD9752ARZRL

Digital To Analog Converters Overview

The AD9752ARZRL is a 12-bit, 125 MSPS high-performance digital-to-analog converter (DAC) from Analog Devices' TxDAC family. It features a segmented current source architecture with proprietary switching to enhance dynamic performance. The device operates on a single +4.5 V to +5.5 V analog supply and supports digital interfaces from +2.7 V to +5.5 V. Key specifications include a settling time of 35 ns, an on-chip 1.20 V reference, and differential current outputs adjustable between 2 mA and 20 mA. It is housed in a 28-lead SOIC package and operates within a temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

• 12-bit resolution with 125 MSPS update rate
• Differential current outputs (IOUTA/IOUTB) with 2 mA to 20 mA full-scale adjustability
• On-chip 1.20 V bandgap voltage reference
• CMOS-compatible digital interface (+2.7 V to +5.5 V)
• Power dissipation of 185 mW at 5 V; 20 mW in power-down mode

Digital To Analog Converters Applications

• Wideband communication transmit channels
• Direct IF architectures
• Base stations and wireless local loop systems
• Digital radio links
• Direct Digital Synthesis (DDS) applications

Digital To Analog Converters Procurement Notes

Verify the 'RL' suffix indicates reel packaging when sourcing. Confirm the specific revision level required for the design. Ensure compatibility with the 28-lead SOIC footprint. Check for RoHS compliance status if environmental regulations apply. Validate that the operating temperature range meets system requirements.

Digital To Analog Converters Selection Notes

Select this component for applications requiring high linearity and low power consumption in transmit paths. The adjustable full-scale current allows optimization of power versus performance. Ensure the host logic levels match the +2.7 V to +5.5 V digital input range. Consider the 35 ns settling time for signal integrity requirements. Verify thermal management capabilities for the SOIC package.

Digital To Analog Converters Part Context

The AD9752 is part of the pin-compatible TxDAC product family, which includes 8-, 10-, 12-, and 14-bit variants. This allows for upward or downward selection based on resolution and cost without changing the PCB layout. The device shares interface options and package styles with other members like the AD9750 and AD9753.

Digital To Analog Converters Replacement Considerations

Pin-compatible alternatives within the TxDAC family include the AD9750 (10-bit) and AD9753 (12-bit, higher speed). Verify that the replacement meets the specific resolution and update rate requirements of the application.
