LTC5582
Electrical Characteristics The l denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. VCC = 3.3V, EN = 3.3V. Test circuit is shown in Figure 1. (Notes 2 and 3).

Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: The LTC5582 is guaranteed functional over the temperature range
–40°C to 85°C.
Note 4: Operation over a wider frequency range is possible with reduced
performance. Consult the factory for information and assistance.
Note 5: The linearity error is calculated by the difference between the
incremental slope of the output and the average output slope from
–50dBm to –5dBm. The dynamic range is defined as the range over which
the linearity error is within ±1dB.
Note 3: Logarithmic Intercept is an extrapolated input power level from the
best fitted log-linear straight line, where the output voltage is 0V.
Typical Performance Characteristics VCC = 3.3V, EN = 3.3V, TA = 25°C unless otherwise
noted. Test circuits shown in Figure 1.
