Hello Stephen,
Welcome to the precision data converters forum!
In both single and continuous modes, BYTE value must be changed to read all 16bits using the parallel bus.
To setup continuous conversion mode and read data, you could do the following…
i am using ads 7825 for data acquisition.
MY PROBLEM:
i am getting fluctuations of around 700mV or so when i read channel 1 giving the same analog input.
also i am not able to read the other channels. (i have attached my code with the message)
…
Other Parts Discussed in Thread: ADS7825 , TMS320F28335 , SN74LVC2G126 Hi,
I want to interface ADS7825 with a dsp board (F28335) whose digital i/o pin voltage level is 3.3v. Can it be done??? If possible, to which pin I should specify that a digital…
Other Parts Discussed in Thread: ADS7825 Hi All,
I am interfacing ADS7825 in serial Interface mode. But I cant read the Data. I have a doubt the SYNOUT is mandatory ? Can any one tried this sucessfully any sample code to read the data.
Thanks in…
Other Parts Discussed in Thread: ADS7825 , ADS8556 Hello everyone,
I am looking for an ADC with the following parameters:
+-10 V input range
+5 V single supply (if it is possible)
2 channels
As many bits of resolution as possible
As much…
Hi Jishnu,
No, you can not change the BW of internal LPF. Also, when you use this ADC to measure a high frequency signal (e.g. 15kHz), your signal will be attenuated and distorted by the LPF. There are two possible solutions:
1. Use an ADC with integrated…
Hi Peter,
Have noticed similar with EK-TM4C1294-XL launch pad ADC noise is quiet high +vRefA directly tied to +3v3. The odd thing is a good part of the sample noise was coming from +5 feeding +3v3 LDO assume the MCU internal 2v0 LDO.
The launch pad…
All very good advice yet LP at this time ADC channels are open inputs simulating analog rising steps driven by residual AXi input gate E charging (Csh), (Rsw) internal resistor and capacitor. Must point out none of that added motor discussion has to do…
