Note:
Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other
parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.
CAUTION: Although this device is designed to be as robust as possible, Electrostatic Discharge (ESD) can damage this device. This device
must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body
or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.
Electrical and Mechanical Specifications
The absolute maximum ratings of the AA116-72LF are provided in
Table 2. Electrical specifications are provided in Table 3.
The state of the AA116-72LF is determined by the logic provided
in Table 4.
Typical performance characteristics of the AA116-72LF are
illustrated in Figures 3 through 6.

Evaluation Board Description
Package and Handling Information
The AA116-72LF Evaluation Board is used to test the performance
of the AA116-72LF digital attenuator. An assembly drawing for
the Evaluation Board is shown in Figure 7 and an Evaluation
Board schematic diagram is shown in Figure 8.
Instructions on the shipping container label regarding exposure to
moisture after the container seal is broken must be followed.
Otherwise, problems related to moisture absorption may occur
when the part is subjected to high temperature during solder
assembly.
Package Dimensions
The PCB layout footprint for the AA116-72LF is shown in Figure 9.
Typical case markings are noted in Figure 10. Package
dimensions for the 5-pin SOT-5 are shown in Figure 11, and tape
and reel dimensions are provided in Figure 12.
THE AA116-72LF is rated to Moisture Sensitivity Level 1 (MSL1) at
260 C. It can be used for lead or lead-free soldering. For
additional information, refer to the Skyworks Application Note,
Solder Reflow Information, document number 200164.
Care must be taken when attaching this product, whether it is
done manually or in a production solder reflow environment.
Production quantities of this product are shipped in a standard
tape and reel format.
