Part Number: ADC-RTD-CONFIG-CALC Other Parts Discussed in Thread: TINA-TI Hello guys,
I am designing a signal conditioning circuit for RTD ( PT100 sensor)
I designed the circuit and got DC analysis graph Voltage vs resistance as linear
I want a graph between…
Part Number: AFE7952 Hi,
I find out a good tool in TI; https://www.ti.com/tool/FREQ-DDC-FILTER-CALC
I set Fs=2900MHz, Interleave=1, Fc=2050MHz, BW=1MHz.
I get: Rx band=850MHz, HD2=1200MHz, HD3=350MHz, HD4=500MHz, HD5=1350MHz

Part Number: PCM1804 Hi team,
When using PCM1804, one of our customers found that the third harmonic generated by ADC in the conversion process is large, which affects the distortion. See the figure for details. The input signal is a single frequency…
Part Number: TMS320F28335 Hi team,
Here's an issue from the customer may need your help:
How to perform harmonic content analysis on an array of sinusoidal waveforms handled by the ADC DMA? TI's FFT library has only the amplitude, phase, frequency…
Hi Sobin,
Please check out the circuits in A Basic Guide to RTD Measurements as the circuits shown relate well to the ADS124S08. The accuracy will depend on how well you perform your system design, PCB layout and whether or not you do any calibration…
Part Number: AWRL6432 Other Parts Discussed in Thread: IWRL6432 HI
Q1,
under fg is 6432 datasheet. I wonder ADC sample rate and ddc(digital down convert) block.
Receive Subsystem have ADC, Decimation and adc buffers.
usually Decimation block is have down…
Hi Dale,
Thank you for the information.
1. ADS131M0x or ADS131E0x ADCs is dedicated to CT/RMS voltage measurements or we can also connect DC Voltage based sensors or 4-20 mA Sensors like Temperature Sensors in Single ended type?
2. Internally, decide…
Hi Bob,
Thank you for your reply.
I have question about ADC-RTD-CONFIG-CALC .
R_PROTECT, R_MISC_H, and R_MISC_L are for protection in case of short circuit, etc,
In an actual circuit, a 1k or several k resistor should be inserted. Is it correct understanding…
Hi Nick
Thank you for the reminder.
To take care of wideband and harmonic distortion, we can filter the data with digital processing after ADC.
The filter recommendation from ADI is with an even higher cutoff frequency, maybe the ADC is good enough in…
Hi,
From the settings described above, IDAC is still turned off.
The IDAC source needs to be turned on, otherwise there is no excitation source to bias the reference resistor and to generate a voltage across the RTD to be measured.
We have some useful…
