Overview

Description

The AD9739BBCZ is a 14-bit, 2.5 GSPS (Giga Samples Per Second) digital-to-analog converter (DAC) from Analog Devices. Designed for high-speed applications, it supports direct RF synthesis and wideband signal generation with excellent dynamic performance.
Key features:
- Resolution: 14 bits
- Max Sample Rate: 2.5 GSPS
- Output Type: Current source (8.66–31.66 mA)
- Interface: LVDS (1.8V/3.3V)
- Power Supply: 1.8V & 3.3V
- Applications: Wireless comms, radar, test equipment, and broadband systems.
The DAC includes an integrated PLL clock multiplier, simplifying clocking. Its high spurious-free dynamic range (SFDR) and low noise make it ideal for demanding RF and IF applications.
Package: 196-ball CSP-BGA.
