LATCH Enable
The AA107-310 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 at IF frequencies where high
attenuation accuracy, low insertion loss, and low intermodulation
products are required. Typical applications include base station,
wireless and RF data 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), least significant bit (LSB) 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 V
DD
2. Set all inputs (SCK, SDA, LE)
Power-down sequence should be the reverse of above.
