AD9742ACPZ

Digital To Analog Converters Overview

The AD9742ACPZ is a 12-bit, 210 MSPS digital-to-analog converter from Analog Devices' TxDAC family. It features differential current outputs ranging from 2 mA to 20 mA and operates on a single 2.7 V to 3.6 V supply with typical power dissipation of 135 mW. The device integrates a 1.2 V temperature-compensated bandgap reference and supports CMOS-compatible parallel data interfaces. Packaged in a 32-lead LFCSP, it offers excellent spurious-free dynamic range performance for wideband applications.

Digital To Analog Converters Feature Summary

• Integrated 1.2 V temperature-compensated bandgap reference
• Differential current outputs (2 mA to 20 mA)
• Low power consumption: 135 mW at 3.3 V

Digital To Analog Converters Applications

• Wideband communication transmit channels
• Direct IF base stations
• Wireless local loops
• Digital radio links
• Direct digital synthesis (DDS)

Digital To Analog Converters Procurement Notes

Verify the package type matches the required 32-lead LFCSP configuration. Confirm that the operating voltage range of 2.7 V to 3.6 V aligns with system power rails. Ensure thermal management strategies account for the specified junction temperature limits and thermal resistance characteristics of the LFCSP package during procurement planning.

Digital To Analog Converters Selection Notes

Select this component when high-speed 12-bit conversion is required alongside low power consumption. The integrated reference simplifies design by reducing external component count. Consider the LFCSP package for compact layouts requiring enhanced thermal performance compared to SOIC or TSSOP options. Verify compatibility with CMOS logic families for digital interface connections.

Digital To Analog Converters Part Context

The AD9742 is part of the pin-compatible TxDAC product family, which includes 8-, 10-, 12-, and 14-bit variants. This allows for flexible component selection based on resolution and cost requirements without changing the board layout. The AD9742 specifically targets applications needing 12-bit accuracy at high speeds up to 210 MSPS.

Digital To Analog Converters Replacement Considerations

Pin-compatible alternatives within the TxDAC family include the AD9744 (14-bit) and AD9740/AD9741 (8-bit/10-bit). These parts share the same interface options and package footprints, enabling upward or downward migration based on performance needs.
