AD9838ACPZ-RL7集成電路（IC）的直接數(shù)字合成（DDS）規(guī)格書PDF中文資料

AD9838ACPZ-RL7屬于集成電路（IC）的直接數(shù)字合成（DDS）。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的AD9838ACPZ-RL7直接數(shù)字合成（DDS）直接數(shù)字合成 (DDS) 用于由數(shù)字信號(hào)生成不同頻率的模擬波形。在必須大范圍掃描的無線系統(tǒng)中可用于頻率控制。主時(shí)鐘頻率有 5MHz、16MHz、16.776MHz、25MHz、50MHz、75MHz、125MHz、180MHz、200MHz、250MHz、300MHz、400MHz、500MHz、1GHz、2.5GHz 和 3GHz，分辨率為 10 b、12 b 或 14 b。

GENERAL DESCRIPTION

The AD9838 is a low power DDS device capable of producing high performance sine and triangular outputs. It also has an on-board comparator that allows a square wave to be produced for clock generation. Consuming only 11 mW of power at 2.3 V, the AD9838 is an ideal candidate for power-sensitive applications.
