Attenuation Display Output

The S5A2250A01 is provided with the DC current output pin for displaying attenuation.

Steps of attenuation from 0 dB -

− ∞ are shown in the table below.

The current of each step is increased or decreased approximately 100/uA.

* Current value may fluctuate depending upon the IC.

When high precision is required use a variable resistor as a load resistor.
