Hello All,

I  want to use AD7151 or AD7156 C to D Converter.  The current consumption is a very critical for the application.

My question is:

What is the current consumption of the AD7151 and AD7156(with one enabled channel) in IDLE MODE?

Best regards…

Hi Everyone,

I would like to detect a metal/non-metal objects using Proximity Capacitive Sensors. I have gone through the web and found AD7151/7150 capacitive sensors. I have gone through the datasheet of those and noticed that when we bring hand closer…

Hi,

I encountered a strange problem while using AD7151 as a capacitance sensor in my current smart hardware design.

AD7151 suffers from serious reading drifting in a specific circumstance where the capacitance should be fixed, but is reported as…

My client wants to use the AD7151 in skin care equipment.

He wants to use it as a standalone (olny ues out signal), with two questions:
1) If it is configured as below figure for skin recognition, can it be used without additional tuning?
2) How many farad…

Hello，

我在使用AD7151测量电容值时，遇到一种特殊的情况，在被测目标电容值（Data Register读数2600左右）较大的情况下，Data Register里的读数（本应该为常量）却每隔大概五分钟增加一。在电容值较小的情况下（小于2600），没有出现这种漂移的情况。

我的外围电路和驱动我反复检查了，应该没有问题。不知道这种情况是否常见，是有可能由什么引起？

谢谢

Hi,

NICE TO FIND YOU ALL HERE!!!

I am using ad7151 for capacitive sensing application..

I use it in fixed mode for continuous sampling.

Ineed to achieve  better response over broad temperature variations during operation.
it is obvious that there is…

我利用AD7151测量电容值，但是DATA REGISTER读出来的值不稳定，还在不断变化
然后我尝试从AVERAGE  REGISTER
读数据，数据还是感觉在不断变化，漂移，怎么解决？

Hello

How to find out the process technologies (CMOS IC processing) for the following ADCs:
AD7466, AD7476, AD7170, AD7151 ?
