  • Product Introduction

Advantages and features:

Low Power (All Operating Conditions): 1.0 W (1 GSPS), 600 mW (500 MSPS) Spoil-free dynamic range (SFDR): 78 dBc (fOUT = 100 MHz) Single carrier WCDMA ACLR = 79 dBc (80 MHz IF) Adjustable analog output: 8.7 mA to 31.7 mA (RL = 25 Ω to 50 Ω) Novel 2×, 4×, 8× interpolator/coarse composite modulators can place carriers anywhere in the DAC bandwidth The auxiliary DAC can control external VGA and offset Multi-chip synchronization interface High-performance, low-noise phase-locked loop (PLL) clock multiplier Digital reverse sinc filter 100-pin, exposed pad TQFP package

Product classification

Digital-to-analog converters (DACs)

Product Details:

AD9776/AD9778/AD9779分别是双通道、12/14/16位、高动态范围Digital-to-analog converters(DAC)，提供1 GSPS采样速率，可以产生最高达奈奎斯特频率的多载波。这些器件具有针对直接变频传输应用进行优化的特性，包括复合数字调制以及增益与失调补偿。DAC输出经过优化，可以与AD8349等模拟正交调制器无缝接口。串行外设接口(SPI®)允许对许多内部参数进行编程和回读。满量程输出电流可以在10 mA至30 mA范围内进行编程。这些器件采用先进的0.18 μm CMOS工艺制造，采用1.8 V和3.3 V电源供电，总功耗为1.0 W，并采用100引脚TQFP封装。

Product Focus

  1. 利用超低噪声与交调失真(IMD)特性，从基带到高中频的宽带信号可以实现高质量合成。
  2. 专有DAC输出开关技术可增强动态性能。
  3. 电流输出配置简便，可以用于各种单端或差分电路拓扑结构。
  4. CMOS数据输入接口，具有可调设置与保持功能。
  5. 新颖的2×、4×、8×插值器/粗调复合调制器可以将载波放在DAC带宽中的任何位置。
