1.

Items in min/max columns in bold italics are confirmed by Test.

2.

Items in min/max columns that are not bold/italics are confirmed by Design Characterization.

3.

The input 0.1dB compression point is a linearity figure of merit. Refer to Absolute Maximum Ratings section for the maximum RF

input power.

4.

Spurious due to on-chip negative voltage generator. Typical generator fundamental frequency is 2.2 MHz.

5.

The power supply voltage must be applied before all other voltages. See Applications Information.
