You are correct, but since these groups are always doing devices for the next rounds of test equipment they always have to do better than anything you can buy. In HD work, source cancellation methods are normally used, one of the very few published references…
Hello,
We have references on TI Precision Labs to help show how to run TINA simulations for stability analysis: Spice Simulation
There are also many other resources on op amp stability and minimizing oscillations referenced in this e2e post here for future…
Hi Steven Park,
Steven Park said: Does the internal reference has a noise spec?
One of my colleagues estimated the noise of the ADS1262 internal reference, see the plot below. Note that this is an estimate and is therefore not a guaranteed spec.
Also note…
Hi Bernhard,
I just wanted to chime in a bit here while others on the team are out for holiday.
Bernhard Boehmer said: Else, please give an example explicitly listing hypothetical values of HD2, HD3, HD4, HD5, HD6, HD7, ... which could show how SFDR could…
Hi Sefa,
On the EVM schematic there is no 1.5V IC for the ADC common mode or the amplifier common mode because in that configuration the VCM for the ADC is generated internally and then the VCM pin of the ADC is outputting 1.5V that is then used as the…
Hello Umar,
Assuming you are using the INA826 with a 510Ω shunt resistor as shown on the original post, with a gain of 97.86V/V:
The input stage offset is Vosi = 150µV (maximum) and the output stage offset voltage is Voso = 700 µV (maximum…
Hi Drew,
we are indeed using ADS54J60EVM on the FMC connector of a Xilinx ZCU102 FPGA.
The input signal is the output of an RF generator plus a mixer to simulate AWGN.
The above spectra are the result of the FFT accumulation over 1sec, the FFT size is…
Part Number: ADS131M04
Hello
We are using the ADS131M04 to measure mains voltage (rms magnitude, phase and harmonic components via FFT). We want to make sure there are 256 samples per cycle (coherent sampling to minimise measurement inaccuracy). This…
Hello,
xi lin said: I am trying to fill in the ADC input impedance equivalency diagram above for the ADS1015. Can you please advise what is C_S (min and max and typ) and C_p1 and C_p2?
The ADS1015-Q1 is a delta-sigma ADC so generally it will appear resistive…
Hi Amrithapriya,
Welcome to our e2e forum! You can use the SAR ADC Drive calculator tool found in the Analog Engineers Calculator as a substitute, that tool is here: https://www.ti.com/tool/ANALOG-ENGINEER-CALC
Our TINA-TI or P-Spice for TI really only…
