Hi team,

I am working on a project where I need to interface AD7888 with a micro-controller (I am using MSP430F6736). The MCU has a SPI interface. Could anyone help me out with the steps from where I need to start and what steps do I need to follow?

Hi,

I have a problem using AD7888 with ATmega324PA.

I am measuring sine voltages f=50Hz, so T= 20ms on 6 channels, 7 and 8 AIN are connected to GND

SPI frequency is 125kHz and SPI mode is 3.

What happens is that from time to time I get one spike…

I see there is linux kernel driver support for the ad7887, but the very similar ad7888 does not seem to have a driver anywhere.  Can I use the same driver?  Can I read all 8 channels using this driver, since the 7887 is only a 2 channel device?

各位工程师，我在做AD7888实验时使用的是单片机控制AD7888的转换。端口定义在P0.0-P0.3。Measure函数就是AD7888的输入和输出函数，函数简单。Main函数就是把转换出来的值给发出来。很简单的测试程序就是出不来。请各位工程师帮忙看下。

附上程序：

#include<reg51.h>                   

#include<intrins.h>

#define uint unsigned int

#define uchar unsigned char

sbit…

想用D7888采样几路电源电压，这几路电压分别为，1.8V，3.3V,24V，想用电阻分压，不知多大电阻合适。原来设计的是1M，实际来看，很不理想。想知道AD7888的输入阻抗有多大？自身是否带跟随器？
