LA4460N, 4461N
Sample Application Circuit 2 : An Example with Minimum Parts
Functional Description on the External Parts
Recommended number of the external parts for the LA4460N/4461N is 8 as shown in the Sample Application Circuit 1.
Namely they are :
· Feedback capacitors
2 pieces 4.7µF/6.3V×2
· Starting time adjustmant resistor 1 pieace 1.5kΩ
· Oscillation compensation capacitor 1 piece
0.01µF
· Oscillation compensation C · R
4 pieces
0.033µF×2, 4.7Ω×2
a) Feedback capacitor CNF
This relates to a low range cutoff frequency fL, and fL lowers with increasing value of the ‘CNF and increases with
decreasing CNF.
b) Oscillation compensation capacitor CX
Signals are applied from the non-inverted NF terminal to the inverted NF terminal through the two CNF capacitors. It
is recommended to connect the oscillation compensation capacitor CX=0.01µF between the floating junction of the
capacitors (minus side of CNF) and GND. As a rule a polyester film capacitor is recommended, but a ceramic type
may be used if a PC board shows good circuit stability.
