AD9785/AD9787/AD9788分别是12-bit、14-bit、16-bit宽动态范围TxDAC®器件,提供800 MSPS的采样速率,允许高达奈奎斯特频率的多载波生成。其具有面向最优化直接变频传输应用的特性,包括复数数字调制,以及增益、相位和失调补偿。优化的数模转换器输出可以实现与模拟正交调制器(如ADI公司的ADL537x系列产品)的无缝连接。1个串行外设接口(SPI)可提供诸多内部参数的编程与回读。满量程输出电流可在10 mA~30 mA的范围内编程。AD978x系列产品采用0.18µm CMOS工艺制造,工作电压为1.8 V和3.3 V,采用100引脚TQFP封装。
The AD9785/AD9787/AD9788 are 12-bit, 14-bit, and 16-bit, high dynamic range TxDAC® devices, respectively, that provide a sample rate of 800 MSPS, permitting multicarrier generation up to the Nyquist frequency. Features are included for optimizing direct conversion transmit applications, including complex digital modulation, as well as gain, phase, and offset compensation. The DAC outputs are optimized to interface seamlessly with analog quadrature modulators, such as the ADL537x family from Analog Devices, Inc. A serial peripheral interface (SPI) provides for programming and readback of many internal parameters. Full-scale output current can be programmed over a range of 10 mA to 30 mA. The AD978x family is manufactured on a 0.18 μm CMOS process and operates from 1.8 V and 3.3 V supplies. It is enclosed in a 100-lead TQFP package.
