Description
LATCH ENABLE
The AA109-310 is a GaAs FET IC 5-bit digital attenuator with a
serial-to-parallel driver packaged in a 32-leadless exposed pad
plastic package. It is particularly suited where high attenuation
accuracy, low insertion loss, and low intermodulation products
are required. Typical applications include base station, wireless
and wireless local loop gain control circuits.

CAUTION: Although this device is designed to be as robust as
possible, ESD (Electrostatic Discharge) can damage
this device. This device must be protected at all times
from ESD. Static charges may easily produce poten-
tials of several kilovolts on the human body or
equipment, which can discharge without detection.
Industry-standard ESD precautions must be employed
at all times.

Serial data (SDA) is shifted into the register on the rising edge of
the clock (SCK), most significant bit (MSB) first. The attenuator will
change states on the rising edge of the latch enable (LE) signal,
according to the most recent 5 bits of shifted data accepted since
the previous falling edge of the LE signal.
Power-up sequence:
0. Connect ground
1. Apply VDD
2. Set all inputs (SCK, SDA, LE)
Power-down sequence should be the reverse of above.
