Typical Component Values:

C1 = 47µF; C2 = C4 = 100nF; C3 = 10µF; C5 = 220pF

R1 = 10k

Ω; R2 = R3 = 10kΩ; R4 = 20kΩ-200kΩ

Recommended Configuration of the not Connected Pins (NC):

Pin 15, 16, 20, 21 = GND

Pin 11, 30 = open (floating)

Pin 24 = open (floating) or VS2

Pin 28 = this pin is not internally connected and may be used for PCB routing

optimization.
