概述

Description

DAC38RF89IAAV is an Analog Devices RF digital-to-analog converter (RF DAC) designed to turn high-speed digital data into an RF analog waveform for microwave/RF front-ends.
Key points:
- High-speed, wide-bandwidth RF DAC with multi-GSPS sampling and current-steering, differential outputs (requires external I/V conversion and RF matching).
- Digital interfaces vary by variant (examples include parallel CMOS/LVDS or JESD204B).
- Common applications: communications transmitters, radar, RF test equipment, and signal generation.
- IAAV denotes a specific packaging/grade variant; exact electrical specs and packaging are in the datasheet.
Note: Always consult the official datasheet for exact specs, recommended circuit layouts, and interface options for your specific lot.

Features

DAC38RF89IAAV features (highlights):
- 14-bit high-speed RF DAC
- Sampling rates up to multi-GSPS for wideband baseband/RF applications
- Dual I/Q outputs for direct RF/baseband synthesis
- JESD204B/LVDS serial interfaces with versatile lane configurations
- On-chip digital calibration and timing alignment for improved SFDR/SNR
- Programmable output current and common-mode voltage to match external reconstruction filters
- Flexible clocking: external reference, programmable PLL options, and clock trees
- Low jitter clock performance and robust spurious characteristics
- Wide operating temperature range and reliable industrial-grade operation
- Available in the IAAV package variant for compact, high-density designs
Note: For exact figures (max sampling rate, SFDR/SNR, output current ranges, etc.), please refer to the latest TI datasheet.
