(Referto Test Circuit).Average operating current can be obtained by the following equation. ICC(opr) = CPD •VCC •fIN +ICC ANALOG SWITCH CHARACTERISTICS (GND = 0 V, TA =25 oC) Symb ol Parameter Test Co ndi ti on Val ue Un it VCC (V) VIN (Vp-p) Sine Wave Distortion (THD) 4.5 4 fIN = 1 KHz RL = 10K Ω CL = 50 pF 0.05 % 9.0 8 0.04 fMAX Frequency Responce (Switch ON) 4.5 Adjust fIN voltage to Obtain odBm at VOS.
