概述

AD8253是一款数字可编程增益仪表放大器，具有G

输入

阻抗、½输出噪声、½失真特性，适合与传感器进行接

口，并驱动高采样速率的模数½换器(ADC)。

AD8253具有10 MHz带½、−110 dB½总谐波失真(THD)，

以及780

ns至0.001%精度的快速建立时间(最大值)。½增益

为

1000时

，失调电压与增益漂移分别为

1.2 V/°C与 10

ppm/°C。除了具有½输入共模电压范围外，在直流至20

kHz，½增益为1000时，这款器件还具有100 dB的高共模抑

制½力。精密直流性½与高速½力的结合，½得AD8253非

常适合于数据采集应用。此外，这款单芯片解决方案还可

简化设计与制造，并通过保持内部电阻与放大器的高度匹

配来提高仪表性½。

AD8253用户接口由一个并行端口组成，用户可采用两种不

同的方法来设½增益(参见图1所示的功½框图)。利用输入

可对通过总线发送的2-bit字进行锁存。另一种方法则是利

用透明增益模式，由增益端口的逻辑电平状态来决定增

益。
