VCC = 3V, EN = 3V, TA = 25°C, unless otherwise noted. Test circuit shown in Figure 1. (Note 2) PARAMETER CONDITIONS MIN TYP MAX UNITS Power Up/Down
Turn-On Time 200 ns Turn-Off Time 800 ns EN = High (On) 0.9 V EN = Low (Off) 0.6 V
Power Supply
Supply Voltage 2.7 5.25 V Supply Current EN = High 5 7 9 mA Shutdown Current EN = Low 0.1 10 µA
Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 3:
The linearity error is calculated by the difference between the may cause permanent damage to the device. Exposure to any Absolute incremental slope of the output and the average output slope from Maximum Rating condition for extended periods may affect device –48dBm to –14dBm. The dynamic range is defined as the range over reliability and lifetime. which the linearity error is within ±3dB.
Note 2:
Specifications over the –40°C to 85°C temperature range are assured by design, characterization and correlation with statistical process control.
