概述

AD5426/AD5432/AD5443

分别是CMOS、8/10/12½、电流

输出数模½换器(DAC)。这些器件采用2.5

V至5.5 V电源供电，

适合电池供电应用及许多其它应用。

这些DAC采用双缓冲三线式串行接口，并且与SPI、QSPI™、

MICROWIRE™及大多数DSP接口标准兼容。采用多个封装

时，还可以通过串行数据输出引脚(SDO)，将这些DAC以

菊花链½式相连。利用数据回读功½，用户可以通过SDO

引脚读取DAC寄存器的内容。上电时，内部移½寄存器和

锁存以0填充，DAC输出处于零电平。

上述器件采用CMOS亚微米工艺制造，½够提供出色的四

象限乘法特性，大信号乘法带½达10

MHz。满量程输出电

流由所½加的外部基准输入电压V

REF

决定。与外部电流至

电压精密放大器配合½用时，集成的反馈电阻R

可提供温

度跟踪和满量程电压输出。

AD5426/AD5432/AD5443

DAC采用小型、10引脚MSOP封装。

提供

EVAL-AD5443SDZ/EVAL-AD5446SDZ/EVAL-

AD5453SDZ评估板用于评估DAC性½。欲了解更多信息，

请参阅UG-327评估板用户指南。

应用

便携式电池供电应用
