Part Number: FDC2112-Q1
Good day, we received query from customer regarding incorrect capacitance readings. The customer is designing a dielectric meter using FDC2112. According to the customer, the measured frequency is correctbut the calculated capacitance values are wrong.
Furthermore, they already checked also this link (FDC2112: the result is false) e2e.ti.com/.../736071
Can you describe more about the capacitance values are wrong ? How far off is the capacitance from expected values ? Also, the FDC2112 is meant for application that can detect a change in the capacitance and not a device to measure absolute capacitance.
What are you sensing today ?

Following graph gives the correlation between measured and correct values
In reply to Sundeep Goel:
Hello, the graph is not well seen. Can you repost this.
Hi, have uploaded xls with readings and graph. Does this help ?
Can you please post a new question with a new topic. This thread was created by a different user.
