Note 1: Absolute Maximum Ratings are those values beyond which the

life of a device may be impaired.

Note 2: Tests are performed as shown in the configuration of Figure 5.

Note 3: Specifications over the –40°C to 85°C temperature range are

guaranteed by design, characterization and correlation with statistical

process controls.

Note 4: The Linear Dynamic Range is defined as the range over which the

output slope is at least 50% of the average slope from –50dBm to –20dBm.

Note 5: The output voltage is settled to the full specification within 1dB.

Note 6: Refer to Figure 1 and Applications Information.

Note 7: Refer to Pin Functions description.
