  • Forum Post: Similar to ADS1232 but 20x faster?

    Chris Kranich
    Poking around for a few hours on the TI site and haven't got a good feel for the right part... I have been using the ADS123x and ADS124x product in digital weight indicators. The sensor is the common wheatstone bridge load cell. These products have an update rate of 30-60/sec and the ADS1232 itself...

  • Forum Post: ADS1243 channel A4-A7 Vol when configured as digital output

    lech lachowicz
    What is the Vol at 200uA when for ADS1243 channels A4 thru A7 configured as digital outputs? The ADS1243 datasheet does not contain a typical or worst case value or graph for channels A4 thru A7 configured as digital outputs (Vol vs current). Is there a graph available for Vol vs current?

    Hi, I am using ADS1247. Can I use AIN1 for positive input and DGND as negative input? i.e. I want counts for the voltage between DGND and AIN1.Is there any way I can do it?

    I got the Application Report SBAA196. I follow the figure 2 to connect electrodes. I want to get the results like figure 9. Can I get the same cure if I put the different positions for the RLD pin? How do I set the registers?

    I received my ADS1281EVAL board and the MMB0 Monday. The software was out of date, so I ran the updater. ADCPro updated correctly, however, software for the ADS1281EVM daughter board didn't and the old software is incompatible with the new ADCPro. I would like to run the new software because I had...

    HI guys, I'm new to the ads1298 so as simple test I'm trying to read DC voltages before I move onto reading ECG signals. I attached 0.7V to IN1P and GND to IN1N. I only display the results every 100mS, but there is a large variation in the readings which is sometimes over 100mV . Below is a...

    No, it is just floating. But if I remember from a previous post, even with it not grounded - at single-ended set up- I should still be able to view the sine wave with no clipping at 0v ? Whereas I see no signal at all, just a slight variation from 0 volts as in the form of noise. http://e2e.ti.com...

  • Forum Post: On ADS1247: Does ADC input have to be bipolar to use full range? I'd like to read positive numbers only but use full ADC range.

    Catalin Cristea
    Hi, The datasheet example (Fig. 85, Pg. 57) Shows a nice way of insuring that Ain0 can go above and below Ain1, so the full ADC range can be used. If I wanted to avoid Rcomp then Ain0 could only be positive relative to Ain1. Does this mean that I would be limited to (less than) half ADC range? ...
