Hi Hal,
Here are the answers to your questions:
Hal Mas said: how I was able to read the voltage of AVDD (5V) using the 2.5V internal voltage ref.
The supply readback voltage is divided by 4, so it should be ~1.25V at all times. This is why you are able…
Part Number: ADS1262 Other Parts Discussed in Thread: TEST , ADS1263 I need to read some radiometric sensors working at UV wavelengths for irradiance measurement. Each sensor is realized with a photodiode short-circuited to a resistor of 1 kOhm, the photocurrent…
Part Number: ADS1262 Other Parts Discussed in Thread: ADS1261 This is an application for a scientific instrument. I have two signals of interest, a sample signal (S) and a reference signal (R) measured simultaneously on the same instrument. My desired…

Hi Team,
I designed a set of circuit by referring to the three-line RTD circuit in THE data sheet of ADS1262. I want to use ADS1262 channel AIN0-AIN5 to measure RTD, and the remaining channel…
Part Number: ADS1262 Q1. I am programming the IC from FPGA with following steps:
step 1. start(pin)=0.
step 2:writing to power register
step3: writing to interface register
step4: writing to mode0 register
step5:writing to mode1 register
step6:writing to…
Hi Stanislav,
I would assume those short DRDY pulses are there to indicate that data is ready to be clocked out. This matches Figure 9-42 in the ADS1262 datasheet. Is there any reason you do not send the RDATA command when DRDY pulses like this? You are…
Part Number: ADS1262 Other Parts Discussed in Thread: TEST I have a thermocouple measurement design using the ADS1262. The design is based on the evaluation boards for the ADS1262 and ADS114. In addition to those base designs I also have an ADS707 differential…
Part Number: ADS1262 Dears:
I use external XTAL for ADS1262, the output have error, but use internal XTAL is normal.
The actual input is 2V, PGA is 1, when use external XTAL, the output skip between 2V and ±2*1/1000. use internal XTAL, output is stable…
Part Number: ADS1262 Hi TI team,
In ADS1262 does all the filter provide 50Hz and 60Hz rejection and for what data rates.
In datasheet
Section 9.3.10(Pg 43)
"The FIR filter provides simultaneous rejection of 50-Hz and 60-Hz power-line frequencies with…
Part Number: ADS1262 Dear sir,
Request you to help me with the following queries:
I am Programming the IC from FPGA.
note:
1.RESET/PWDN pin always high, and using internal reference ,continuous conversion, gain 32, mux reg-- AIN0(POSITIVE ),AIN1(NEGATIVE…
