Any combination of the above states will provide an attenuation

approximately equal to the sum of the bits selected.

Application Circuit

DC Blocking Capacitors C1 & C2 are

required on RF1 & RF2. Choose C1 = C2 =

100 pF ~ 0.1 uF to allow lowest customer

speciﬁc frequency to pass with minimal

loss. R1= 5K Ohm is required to supply

voltage to the circuit through either Pin 11

or Pin 14.

Suggested Driver Circuit

(One Circuit Required Per Bit Control Input)

Simple driver using inexpensive standard logic ICs provides fast switching using minimum DC current. * Recommended value

to suppress unwanted RF signals at V1 - V5 control lines.
