DAC39J82IAAV

Digital To Analog Converters Overview

The DAC39J82IAAV is a dual-channel, 16-bit digital-to-analog converter from Texas Instruments. It operates at a sampling rate of 2.8 GSPS with four current outputs. The device features JESD204B interface support and accepts CML or LVPECL input types. Key performance metrics include a settling time of 10 ns, differential nonlinearity (DNL) of 4 LSB, and integral nonlinearity (INL) of 6 LSB. Gain error is specified at 2%/FSR. Power consumption is approximately 1.1 W to 1.135 W. It functions within an operating temperature range of -40°C to +85°C and is housed in a 144-FCBGA package.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against official Texas Instruments documentation to confirm pinout and electrical specifications. Ensure compliance with export control regulations as indicated by distributor listings. Confirm moisture sensitivity level handling procedures prior to assembly to prevent package damage during reflow soldering processes.

Digital To Analog Converters Selection Notes

Select this component when dual-channel 16-bit resolution at 2.8 GSPS is required. Compare against the DAC39J84IAAV if four channels are needed instead of two. Consider the FCBGA-144 package constraints for PCB layout. Verify power supply requirements match the 3.3 V analog and 0.9 V digital voltage domains specified in the datasheet.

Digital To Analog Converters Part Context

This part belongs to the DAC39J8x family of ultra-high-speed DACs designed for advanced communication and radar systems. It shares architectural similarities with the DAC37J82 but offers higher speed and additional output channels compared to lower-tier models. The IAAV suffix denotes a specific commercial grade variant within the broader product line.

Digital To Analog Converters Replacement Considerations

The DAC39J84IAAV serves as a functional substitute offering four channels instead of two. Direct pin-for-pin replacement requires verification of channel count compatibility and software configuration adjustments. No other direct equivalents are confirmed in public documentation.
