Part Number: ADS7804 Hi, I have a components question that needs to be answered for one of the thermal analysts. The datasheet for the ADS7804UB part says that normal operation is up to 85C. It also states that it can operate in a derated condition up…

Hello Tom,
This thread will be moved to the precision data converters forum.
Since the ADS8504 was specifically designed to be the upgrade for the ADS7804, there isn’t another device that is pin-to-pin compatible with the ADS7804.
Please note that…
Hi Somnath,
Welcome to the data converts forum!
About the REF3125, 2.503V is within specs. The REF3125 has a +/-0.2% accuracy, so its expected output is a value between 2.495V to 2.505V.
A common issue when using the ADS8505 is that a non-200ohm…
Hi Peter,
Have noticed similar with EK-TM4C1294-XL launch pad ADC noise is quiet high +vRefA directly tied to +3v3. The odd thing is a good part of the sample noise was coming from +5 feeding +3v3 LDO assume the MCU internal 2v0 LDO.
The launch pad…
All very good advice yet LP at this time ADC channels are open inputs simulating analog rising steps driven by residual AXi input gate E charging (Csh), (Rsw) internal resistor and capacitor. Must point out none of that added motor discussion has to do…
