ELECTRICAL CHARACTERISTICS The
l
denotes the specifi cations which apply over the full operating temperature range, otherwise specifi cations are at TA = 25°C, VCC = 5V, EN = 5V, unless otherwise noted. Test circuits are shown in Figures 1 and 3. (Notes 2 and 3). PARAMETER CONDITIONS MIN TYP MAX UNITS Enable (EN) Low = Off, High = On
EN Input High Voltage (On) l 2 V EN Input Low Voltage (Off) l 1 V Enable Pin Input Current EN = 5V l 68 μA Turn ON Time VOUT within 10% of Final Value, C1 = 22nF 1 μs Turn OFF Time VOUT < 0.1V, C1 = 22nF 5 μs
Power Supply
Supply Voltage l 4.75 5 5.25 V Supply Current 26.5 32.5 mA Shutdown Current EN = 0V, VCC = 5V 0.1 100 μA
Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 3:
A 1:4 input transformer is used for the input matching to 50Ω may cause permanent damage to the device. Exposure to any Absolute source. Maximum Rating condition for extended periods may affect device
Note 4:
Operation over a wider frequency range is possible with reduced reliability and lifetime. performance. Consult the factory for information and assistance.
Note 2:
Specifi cations over the –40ºC to +85ºC temperature range are
Note 5:
The linearity error is calculated by the difference between the assured by design, characterization and correlation with statistical process incremental slope of the output and the average output slope from controls. –30dBm to 2dBm. The dynamic range is defi ned as the range over which the linearity error is within ±1dB. 5570f 4
