Other Parts Discussed in Thread: LDC1614
Hi team,
I have a question about sensor coil design for LDC1614.
In page 24, 4.2.2 of LDC Sensor Design application note (SNOA930A), there is a description as below.
- Keep the inner 30% of the sensor area unwound for most applications, but for inductive metal button
replacement place as many turns as possible.
Q1. Could you advise what is the purpose of keeping 30% of unwound area in center of the coil?
Q2. How critical is this 30%?
Q3. which types of application doesn't require this unwound area?
regards,
