Part Number: ADS1225 Tool/software: Hi team, We have a problem with the ADS1225 on some boards. When we apply the supply voltage, the DRDRY pin remains high for 17 ms. Temperature of ADS1225 is 20 degrees. Image ADS1225(20 degrees). When we cool down…
Part Number: ADS1225 Hi team, Is there an upper limit to the resistance value of the RC filter placed at the input? If the resistance value is too high, will the ADC result malfunction? If you have a document that determines the constants, please let…
Part Number: ADS1225 Goal
Understanding the timing criteria required for using the Input Buffer
Issue
The datasheet has the statement "Note that when START is low, the buffer must be disabled to prevent loading of the inputs." (Page 14)
For a…
Part Number: ADS1225 Hi team, I'd like to know about Self-Calibration. When my customer use self-calibration, they get a difference in the output data. Could you check their waveforms? And then, I have some questions about self-calibration. 1. Self-calibration…
Part Number: ADS1225 Hi team, I'd like to know about the aging for gain error and offset. Do you have the consequences of changes over time for offset and gain error? Sincerely. Kengo.
Part Number: ADS1225 Other Parts Discussed in Thread: ADS1220 What is the maximum rise time permitted on the START and SCLK pins of the ADS1225? Want to add R-C for noise immunity.
Dear Joachine,
many thanks I2C it's not a problem.
And probably it's better because the PGA = 4 and the second differential channel
Many thanks
Best regards
Gianluca

what kind noise/spike (input or VDD) will cause the digital output latch to ffff? only can be reset by remove power.
Thanks…
Part Number: ADS1225 Other Parts Discussed in Thread: ADS1220 Hi teams,
My customer wants to know what recommended to be connected the exposed pad to anything.
I think this is recommended to be connected to GND.
And, in the datasheet the recommended…
Part Number: ADS1225 Other Parts Discussed in Thread: ADS1220 Dear Specialists,
My customer is considering ADS1225.
He'd like to know recommended PCB layout.
I confirmed product folder, but there are no information from ADS1225 datasheet, no EVM…
