Hi Jon,
For the filter equation you would use just Rfilter as opposed to 2*Rfilter.
As to the need to use 5V as opposed to 3.3V for the analog supply, the extended range is only required if the input voltage should exceed 3.3V. In the case of the single…
Part Number: ADS122U04 Hello,
I have a question regarding ADC gain in the ADS122U04. In our system we are taking a single ended measurement using a gain of 2 and a vref of 2.048V. I am using the equation LSB = (2 x vref / gain) / 2^24, and then multiplying…
Hello Bob,
I have purchased a Gems (UK) make Ratiometric Pressure Transducer - that measures 0 to 16 bar pressure and gives a corresponding output of 0.5 to 4.5VDC. [note: MEAS or Baumer make that works on 5vdc was not available immediately, so went for…
Part Number: ADS122U04 Other Parts Discussed in Thread: ADS1220 , , ADS122C04 Hi Expert,
Can you help clarify the difference between ADS122U04 and ADS1220?
Is digital interface the only difference? (ADS122U04 UART, ADS1220 SPI)? If not, any other upgrade…
Part Number: ADS122U04 Hello Bob, Thank you for replying to my earlier query regarding ADS122U04 interfacing with RTD PT100. In the same project I also need to use ADS122U04 for measuring Engine Oil pressure (in heavy vehicles) - using MEAS make M5100 series…
Hello Bob,
Thank you for your inputs.
As you suggested, I did the following:-
a) After Microcontroller powerup [and initialization of UART1 (for communication with
ADS122U04) and UART5 (for sending out values to PC for debug purpose)] , I just sent out…
Part Number: ADS122U04 Hello Bob,
What is the easiest way to convert 24bit A/D converted output of ADS122U04 into Temperature into Degree Centegrade?
I have exactly followed the datasheet of ADS122U04 and assembled it's circuit on a general purpose PCB…
Part Number: ADS122U04 Tool/software: Code Composer Studio Hello I have MSP430 and ADS122U. It`s nedded to recive data from ADC and then transmit to the terminal. RXBUF of MSP430 have 1 byte (first picture). ADC send after reqirer 4 bytes (second picture…
