Because AD7152 is last time buy but customer is looking for fast response time which is less than 5ms or below.
Does AD7152 have next generation product or could you give me advise ,tks!
Competitor TI FDC1004
I am currently working on a project to measure the capacitance in a relatively fast signal. I came across AD7152 and bought the development board. Working on a single channel, I can get a sampling frequency of 200Hz, however, I would like to get…
I am currently working with the Eval-AD7152EBZ.
I am using this board to measure pressure/weight by using a variable capacitor
This works nice but I want to make more of these pressure sensors on the same I2C bus.
But the with the AD7152 it…
I'm in the process of gathering information for designing the sensor for one of the capacitance digital converters like the AD7152. I'm looking to build a system that will measure the moisture in soil, so I need the measure the capacitance of…
the way the AD7745 is designed, it is not possible to useexternal excitation sources.
The excitation source is not only to provide voltage levels, italso controls and synchronises the CDC measurement. In application note AN-1055on page…
The capacitive proximity sensors described in AD714x AppNote 830 are contact-less.
What I'm unsure about is the achievable precision (distance, repeatable) with
capacitive proximity sensors (AD714x) or Cap2Dig converters (AD715x/AD774x).
I am looking for a Capacitive to Digital converter of which the sampling frequency is bigger than 1KHz and the Conversion frequency is bigger than the sampling frequency and the resolution should be in fF level.Does someone have a good advice…
