Note 4

†Electrical Characteristics are over Recommended Operating Conditions unless otherwise stated.

‡Typical figures are at 25°C with nominal +5V and are for design aid only.

Note 1: All of the above test conditions use a test source impedance which matches the device’s impedance.

Note 2: dBm is referenced to 600Ω unless otherwise stated.

Note 3: These parameters need to be taken into consideration when designing or specifying the power supply.
