概述

一个封装中集成两个12位DAC
DAC梯形电阻匹配：0.5%
超小型DIP和表面贴装封装，节省空间

四象限乘法
低增益误差（整个温度范围内最大值为1 LSB）
快速接口定时

AD7547在单芯片上集成两个12位电流输出DAC，内置电平转换器、数据寄存器和控制逻辑，可以与微处理器轻松接口。它有12路数据输入CSA、CSB、WR控制DAC选择与加载。数据在WR上升沿锁存至DAC寄存器中。该器件与大多数微处理器速度兼容，并且接受TTL、74HC和5V CMOS逻辑电平输入。

该数模转换器提供四象限乘法功能，具有单独的基准电压输入和反馈电阻。单芯片结构则可确保出色的散热和增益误差跟踪特性。在整个温度范围内，两个DAC均能保证12位单调性。

AD7547采用线性兼容CMOS (LC²MOS)工艺制造，因而能够在同一芯片上实现快速数字逻辑与精密线性电路。
