Part Number: ADS7046 Hello everyone,
I am currently working on the ADS7046 ADC and an STM32H745 microcontroller. However, I am facing challenges regarding accurate waveform sampling via SPI. My objective is to sample a waveform with a frequency of up…
Part Number: ADS7046 Other Parts Discussed in Thread: OPA855 , TINA-TI Hello Team, We are planning to use the ADC ADS7046 for one of our applications. The input is from a trans-impedance amplifier using the opamp OPA855 The photodiode we are using is J-Series…
Part Number: ADS7046 Hello team,
What is the input impedance of AINP & AINM of ADS7046?
If the input impedance varies with frequency, then I would like to know the impedance at 250kHz.
Best Regards,
Kei Kuwahara
Part Number: ADS7046 What is the behaviour of the internal sampling capacitor(s) at the end of each conversion? Are the sampling capacitors reset/discharged after every conversion? I can't see a clear answer to this in the datasheet.
Part Number: ADS7046 Other Parts Discussed in Thread: ADS7042 We use the ADS7042 in our design. The ADS7046 seems identical except for the 3MSPS sample rate specification. Is that true. Will this part be compatible as a drop in replacement for ADS7042…
Part Number: ADS7046 Other Parts Discussed in Thread: ADS7049-Q1 , ADS7042 Hi Team,
my customer uses ADS7046 in his project. Since we have no EVM for this device, is it possible to modify/equip one of these EVMs to the ADC:

Part Number: ADS7046 Hi Team,
My customer uses the ADS7046 in his product. In the datasheet they don't find the input capacitance/impedance of the pin SCLK (me neither). Could you please check if you have these values. The customer need to know that…
Part Number: ADS7046 Hello,
My customer has the following question:
I have a question about the offset and gain error of the ADS7046, hope you can help me.
In the Datasheet the offset and gain error is given only after calibration.
If we going to use…

Hello Team, We want to design a trans-impedance amplifier (TIA) using the opamp OPA855. The ADC we are using is ADS7046. The photodiode we are using is J-Series SiPM Sensors . What is the…
Øyvin,
The best way to set the acquisition time to make sure that you get good settling is to do a simulation and look at the settling response. Even though the output of the op amp is connected to an RC the circuit is not a simple second order…
