DAC38J82IAAV

Digital To Analog Converters Overview

The DAC38J82IAAV is a dual-channel, 16-bit digital-to-analog converter (DAC) from Texas Instruments. It supports a maximum sampling rate of 2.5 GS/s with a maximum input data rate of 1.23 GSPS. The device features a JESD204B interface supporting up to 12.5 Gbps per lane across eight configurable serial channels. It includes an on-chip low-jitter PLL, a 48-bit NCO, and complex mixers for direct upconversion. The analog supply voltage is 3.3 V, while the digital supply is 900 mV. Operating temperature ranges from -40°C to +85°C in a 144-ball FCBGA package.

Digital To Analog Converters Feature Summary

• Integrates a high-performance low-jitter PLL and flexible digital signal processing blocks including a 48-bit NCO and complex mixers.
• Supports JESD204B Subclass 1 for deterministic latency and multi-device synchronization via SYSREF.
• Provides four analog outputs with flexible routing from two internal digital paths through an output multiplexer.

Digital To Analog Converters Applications

• Wireless infrastructure base stations
• Software-defined radio systems
• Direct RF transmission architectures

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'AAV' against the manufacturer's current datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure that the JESD204B link parameters, such as lane count and LMFS configuration, are compatible with the host FPGA or processor interface before finalizing procurement.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel architecture with 16-bit resolution and 2.5 GS/s throughput is required. It is suitable for designs needing integrated digital upconversion capabilities and JESD204B connectivity. Compare against the DAC37J82 if a lower 1.6 GS/s sampling rate is sufficient for the application bandwidth.

Digital To Analog Converters Part Context

This part belongs to the DAC3xJ82 family, which also includes the DAC37J82. The DAC38J82 variant specifically offers the higher 2.5 GS/s sampling rate compared to the 1.6 GS/s limit of the DAC37J82. Both share similar pinouts and functional blocks, facilitating potential design upgrades within the same platform.

Digital To Analog Converters Replacement Considerations

The DAC37J82IAAV is a pin-compatible alternative with a reduced maximum sampling rate of 1.6 GS/s. Verify if the lower speed meets the system requirements before substitution.
