Description

M/A-COM’s AT90-1413 is a GaAs FET 4-Bit digital attenuator with integral driver. Step size is 1 dB pro- viding a 15 dB attenuation range. This device is in an PQFN plastic surface mount package. The AT90-1413 is suited for single supply applications where accuracy, fast speed, low power consumption and low costs are required. For dual supply designs without switching noise, use AT90-0413.

  1. Pins 10 & 29 must be isolated. 2. Vee is produced internally and requires a .1 µF cap to GND. Generated noise is typical of switching DC-DC Converters. 3. The exposed pad centered on the package bottom must be connected to RF and DC ground. (For PQFN Packages)

During turn-on, the device requires an initial start up current (Icc) specified as “Turn-on Current”. Once operational, Icc will drop to the specified levels. 5. The DC-DC converter is guaranteed to start in 100 µs as long as the power supplies have the maximum turn-on current available for start- up.

Handling Procedures Please observe the following precautions to avoid damage: Static Sensitivity Gallium Arsenide Integrated Circuits are sensitive to electrostatic discharge (ESD) and can be damaged by static electricity. Proper ESD control techniques should be used when handling these devices. Moisture Sensitivity The MSL rating for this part is defined as Level 2 per IPC/JEDEC J-STD-020. Parts shall be stored and/or baked as required for MSL Level 2 parts.
