Hi Everyone -
As you well know (I certainly do at least), trying to find detail on a part or an application can be difficult.
What's the best part to use in this (insert your favorite here) situation?
What will happen if I have an input signal applied to an ADC while there is not power applied to the pins?
Who let the smoke out of my chip?
I've read every word in the data sheet and I still can't get any data from this stupid part! What's wrong with this chip?
Please feel free to provide feedback to me or anyone on my team (Greg, Rafa, Tony, Kevin, Luis, Bob, Chris or myself) by posting your favorite rant here and we'll try to resolve it for you.
I am using ADS1248 for RTD measurement, I need a step by step calibration procedure to take care of static errors like gain, offset etc.
Could you please give me some idea about calibration of ADS1248 device?
I'm new to forums and converstations, so I don't know if this is the proper place for this question, but I'm looking for a 24bit, 5k SPS (+) adc to use in a strain gauge weigh scale application. Can anyone help me out with a suggestion and possibly application information?
I need help to select an ADC for my application.
The experiment I am designing is a precision optical displacement sensor for a small satellite (CubeSat). Signal processing is done on a DSP and I need to design the circuits to convert the analog sensor signal and feed it into the DSP.
The output of one sensor (a pair of two photodiodes) are two single ended DC signals and one differential AC signal which is modulated at frequencies up to 20 kHz. I have four of these sensors that I want to sample. At least two each need to be sampled synchronously, ideally all four would be sampled synchronously.
Since the application is on a small satellite, the power consumption is critical. The sensor is supposed to have a high dynamic range, therefore a 16bit ADC is required.
Can you recommend an ADC for this application? Do you need further information about my project to assist me with the selection?
I have been looking for an ECG simulator, tester. Could you tell me what brand TI used in the ADS1298 video so I can look for it?
Thanks in advance,
Hi Victor - we use two different simulators, one is the CardioSim from BioMetric Cables in Bangalore and the other is a high end model from Fluke
Hi Rajesh, did you get your calibration procedure question answered?
Hi Vette Man - did you find an appropriate ADC or are you still looking? Can I ask why you need such a high sample rate for a weigh scale application?
I am working on ECG holter with ADS1296. I have question about Input Common-Mode Range of PGA.
For gain = 1, and Umax_diff = 2.4V = Uref, CM is in boundaries from 1.4 to 1.9 volts. Now, how to drive patient to that common voltage, through RLD or externally with resistive divider which isn't practical?
Whether it will be done, if I set CONFIG3.RLDREF_INT = 1, in fact set the reference for RLD amplifier on (AVDD + AVSS)/2?
I am sorry if the question is stupid, but I am little confused with that.
