Other Parts Discussed in Thread: ADS1241ADS1241 is configured as 4 independent differential input channels. 6 boards are built and 2 boards show adnormal behaviour when nothing is connected to the input channels. See below for the waveforms.

Other Parts Discussed in Thread: ADS1241 Regarding the ADS1241, I would like to know if you can recommend a
sequence for reading 4 channels by means of polling DRDY via SPI. I am
not sure how to avoid reading corrupt data from the output register.…
Other Parts Discussed in Thread: ADS1241 The ads1241 is a 24-bit A/D. I am controlling the A/D with a uP via a SPI interface.
I have having a problem figuring out the meaning of the "Full Scale Resolution" (FSR) registers in the A/D. The register…
Hi Stanislav,
Can you share the part number for the Pirani gauge?
The ADS1248 reference cannot go that low, however the ADS1240, ADS1241, ADS1242, or ADS1243 may be a candidate as it's reference can be a lower magnitude, 100mV to 5V.
Let me check…
Part Number: ADS1256 Other Parts Discussed in Thread: ADS1234 , ADS1232 , , ADS1241 , ADS1235 , ADS1248 , ADS124S08 , ADS1261 Hi! I am redesigning an old board that uses ADS1232/ADS1234, using a faster processor to read scale weight. One thing that today is a…
Part Number: ADS1258 Other Parts Discussed in Thread: ADS1241 , Hello, all! I have a simple question: XTAL pins in ADS1258 datasheet named XTAL1, XTAL2; who is who, input/output? In new design I want to place series resistor to 32768 Hz crystal, same as…
Ikon,
1. It looks like the you could connect it to the LMP2231 as shown in the datasheet even if it outputs voltage. However since this circuit provides gain, you may not need it since the ADC can provide gain as well.
2. It may not look like there…
Hi Jim,
I tried getting ahold of you earlier today and did talk to Mark. I told Mark I would do some investigation on any required delay following DRDY going low. I did not find any specific information for the ADS1217, but I did find some information…
Greg,
I don't usually review ADS1258 posts, but I do have some relevant information. I've written a response to a post for the same type of question for the ADS1241 recently and you should review the post to try the same thing. Below is a link to the…
