Hirotaka-san,
One other possibility would be the ADS1248 if you need four channels. This device has an input multiplexer capable of four independent channels. If the device is run at 1kSPS or 2kSPS, you could get measurements for each input at faster…
Hi Uchikoshi-san,
I do not know why we do not have a clock duty cycle specification in the ADS1255 datasheet. I would recommend going by the duty cycle specification given in the ADS1257 datasheet as a more conservative approach, as this is a similar…
Hi Joachim,
If i were to change the requirements to only 2 or 1 channel, how would your recommendations change?
The ADS1257 looks quite attractive to my application! Thank you!
Hi Eduardo,
So the DDC232, DDC1128, DDC264 are current-input ADC. Can I use it as a regular ADC that reads a change in voltage input and convert to Digital Signal (like an ADS1256 ADS1257)?
Does it only read current value? If this cannot read voltage…
Hi Takumi-san,
Your reasoning is correct. I would make a couple of additional comments to your analysis:
By using +/-10 ppm (20 ppm), you are effectively doubling the INL error which never exceeds 10 ppm. Therefore, I would propose that the worst…
Hi Ignacio,
For the first question, I would recommend you to check with the Precision Data Converters team in their forum.
For general observations regarding the THS4551 circuit,
1. What is the supply voltage being applied to the THS4551? Is it…
Hi Guru,
The ADS1263 has a second 24-bit ADC; however, it only goes up to 800 SPS and has an ENOB of 14 bits...For the ADS1262 or ADS1263, the primary 32-bit ADC can operate at 38.4 kSPS, however, the resolution is only 15 bits at this data rate. ENOBs…
Hi Ganesh,
For seismic exploration, the ADS1281 and ADS1282 are the devices that we recommend for that application. Typically, some of the main concerns are the ADC's AC performance and power consumption, and these devices are optimized in those areas…
Other Parts Discussed in Thread: ADS1257 , ADS1247 , ADS1248 Hi,
in the section Hardware-Compensated, Three-Wire RTD Measurement Example (here attached) at page 51 in the ads1257 datasheet, I have seen that there is a differential swing of ±14.7mV…
Part Number: LDC1612
I have LDC1612- H coil
I want to repeat the process of finding L,Rs, Q, C values
And Plot the Graphs for L ,Q , Rs,C Vs Frequency
I know the formula for quality factors = Rp* square root of (C/L)
How to calculate Rp?
How…
