DAC38RF82IAAV

Digital To Analog Converters Overview

The DAC38RF82IAAV is a dual-channel, differential-output, 14-bit RF-sampling Digital-to-Analog Converter (DAC) manufactured by Texas Instruments. It supports a maximum sampling rate of 9 GSPS and features an on-chip Phase-Locked Loop (PLL) with Wide-Band Interpolation capabilities. The device utilizes a JESD204B interface for data input. Key electrical parameters include a resolution of 14 bits, a sampling rate of 9 GSPS, and two channels. It operates within a temperature range of -40°C to +85°C and is housed in a 144-FCBGA package.

Digital To Analog Converters Feature Summary

• Integrates a high-performance on-chip PLL and VCO for flexible clocking configurations.
• Supports wide-band interpolation modes ranging from 2x to 24x for composite baseband transmission.
• Features a low-power JESD204B interface supporting multi-chip synchronization.

Digital To Analog Converters Applications

• Wideband digital upconverters for communication systems.
• Composite baseband transmitters requiring high bandwidth synthesis.
• RF signal generation applications utilizing direct RF sampling techniques.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix to ensure the correct package variant and moisture sensitivity level match your design requirements. Confirm that the component meets RoHS compliance standards for your region. Check the latest datasheet revision for any updates to pin definitions or electrical characteristics before finalizing the bill of materials.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel architecture with 14-bit resolution at high speeds is required. Ensure the system design accommodates the 9 GSPS maximum output rate and the specific voltage levels for analog and digital supplies. Verify that the host processor can support the JESD204B interface protocol and lane rates specified in the documentation.

Digital To Analog Converters Part Context

This part belongs to the DAC38RF8x family of high-speed RF-sampling DACs from Texas Instruments. The family includes variants such as the DAC38RF80, DAC38RF83, and DAC38RF87, which share similar architectural features but may differ in specific performance metrics or interface configurations. The IAAV suffix typically denotes a specific commercial grade and packaging option within this product line.

Digital To Analog Converters Replacement Considerations
