Operating Instructions
The
AM55-0024
can
operate
with
voltages
between +3 V and +5 V. The amplifier voltages are
applied to pins A2, A3, B2 and B3 respectively.
A1 and B1 supply the Vdd to the logic circuits and
thus must be the same levels as the logic driving
the Clock, Latch Enable and Data ports.
The
amplifiers and logic circuits are independent and
need not be the same levels.
Serial Interface
Each channel in the AM55-0024 is independently
controllable with a 3 wire serial interface: Clock,
Data, and Latch Enable.
These lines can be
shared based on application requirements.
The
attenuator within the device is controlled with a 6 bit
word, enabling the selection of 64 possible states.
The highest gain state is '000000', and the lowest is
'111111'. The sequence for shifting the data is as
follows:
Present data (Least significant bit first),
strobe clock, repeat until 6 bits have been
presented and clocked, then strobe the latch
enable line, which implements the state change.
