Hi Andrea,
Welcome to the TI E2E Forums!
The ADS1261-Q1 has 6 analog input spins, which allows for up to 3 fully-differential inputs, or 5 single-ended inputs when one pin is dedicated as a common reference. The ADS1261-Q1 measures all input voltages…
Hi Nimit,
I still don't have all of the information regarding your setup. For example, do you have any connection from your micro to the CLKIN, START, RESET and PWDN pins? Or are you just using the default conditions of the EVM hardware?
The CLKIN…
Hi Theodore,
Can I ask what you hope to gain by chopping the excitation polarity using AC excitation? You may not get the results you are expecting relative to the effort involved. AC excitation will only remove the error and offset of the load cell…
Hi Gianfranco,
Welcome to the TI E2E Forums!
With the provided ADCPro software, I don't know of an easy way to implement AC excitation... The problem is that ADCPro only lets you configure the ADC registers once, and then collect a block of data for…
Part Number: ADS1262 Other Parts Discussed in Thread: INA125 , ADS1235 , OPA388 , ADS1261 Hello people!
With ADS1262 PGA set on Gain 32, the full scale is 78mV, so my load cell -with its 20mV max output- isn't able to exploit ADS capabilities. I have…
Hi Cleber,
It would be helpful from the start to know your specific requirements. The ADS1232/34 runs at slow data rates to achieve the lowest level of noise. The ADS1232/34 also uses a full-scale range that is +/- 0.5Vref/GAIN which allows better dynamic…
Part Number: ADS1260 Hello,
If I configure the internal reference according to the data sheet, I always get the REFL_ALM (Reference Alarm) error.
It's explained quite simply in the data sheet but it doesn't work.
I write 0x10h to register REF. …
Dear Trailokya
Please find attached the full schematic of the PCA. 5V_REF connections are marked with red boxes. I removed BR1 (the pressure sensor bridge). The bridge is connected to the 5V_REF through the TMUX1111RSVR switch (U4). The output is still…
Part Number: ADS1260 Hello,
I haven't tried configuring the ADC to output VBIAS (2,5V) on the AINCOM pin yet. Attached is the configuration for the ADC, I was able to read it out correctly. AVDD = 5V.
id = 0xA1h
status = 0x06
mode0 = 0x28h
mode1…
