No.855-6/7
Sample Application Circuit : LA2110 & LA3375
Note : When using the sample application circuit :
1. Separation adjustment is performed with 10k
Ω variable resistance in low-pass filter.
2. Change noise detection sensitivity control Rs to an adequate value for strong or medium electric field.
3. Adjust noise AGC with CY, RY for effective noise suppression in a medium or weak electric field.
4. Adjust pilot cancel degree with variable resistance of 50k
Ω connected to LA2110 pin 15.
5. By changing the 1
μF capacitor between LA3375 pin 11 and 12, pilot cancel follow-up response time can be changed.
But if the value is decreased, distortion factor, etc. will be adversely affected.
