Yes,I currently think that AD7156 uses with the adaptive threshold mode.
Regagrding the on/off timing, this system is not constant. This system which I mention is irregularly turned on/off.
Regarding on/off switch of this system, the accelerometer…
I am using Eval AD7156 for liquid level measurement application. I would like to add reference capacitance in one channel and level measurement in another channel. Here my doubt is should I connect EXC1 and EXC2 short together??
we already started to use the AD7156 C to D convertor and the results are very good.
Working with the chip we saw the next:
1. The chip is in "Power-down mode" - configuration reg is: 0x13. When reading the "Status register" BIT7 is…
AD7156 x AD7147
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?
In recent years, to have more applications will often use Contactless capacitive Sensor App. If using AD7150/AD7156 Proximity Sensing furthest can be detected in a number of normal distance. ADI has actual test data this area can be provided…
AS per the device power dissipation, we have selected AD7156/7 with output RMS noise of 1.6u. Please confirm whether they are suitable to use with this device.
Advance Thanks & Regards,
I use the AD7156 capacitance to digital converter in a sensor application where I sample a capacitance value at 20 hz.
In my application i use a micro controller to setup the AD7156 via i2c to continuos conversion, 1 pico farad range and the…
