Other Parts Discussed in Thread: ADS7805
Hi,
My customer used the reference circuit as followed. The AD input is the output from an amplifier. Customer found our device's accuracy performance can't meet their requirement.
We tried to change the parameters, change the 200ohm to 50ohm, change the two 2.2uF Tantalum cap to 2.2uF ceramic cap. And the performance can meet the customer's requirement.
Is there any problem for these changes? How about the function for the 200ohm resistor and how to choose the value of this resistor? Thanks!
