Truth Table Pin Function Pin Name Enable Disable Low Gain High Gain Low Gain High Gain Circuit Bias VCC1 VCC1 1111 Toggles Gain Mode (Active or Bypass) GAIN 0101 Toggles LNA On/Off ENABLE 1100 LNA Bias VCC3 LNA Out 1111 NOTES: 1. Logic state "1" equals VCC voltage. Logic state of "0" equals ground potential. 2. VCC3 is inductively coupled to LNA OUT pin 3. Minimum logic state “1” for enable and gain pins is 1.25 V. 4. Minimum logic state “0” for enable and gain pins is 0.8 V. Table 4. Electrical Characteristics Measured in Frequency Specific Tuned Circuits (continued) (VCC = 2.75 V, TA = 25°C, Rbias = 2 kΩ, unless otherwise noted.) Characteristic Symbol Min Typ Max Unit |
