PIN AND FUNCTIONAL DESCRIPTIONS
AIN+, AIN–, GSX
Transmit analog input and transmit level adjustment.
AIN+ is a non-inverting input to the op-amp; AIN– is an inverting input to the op-amp; GSX is
connected to the output of the op-amp and is used to adjust the level, as shown below.
When not using AIN– and AIN+, connect AIN– to GSX and AIN+ to SG. During power saving
and power down modes, the GSX output is at AG voltage.
AG
Analog signal ground.
AOUT
Analog output.
The output signal has a maximum amplitude of 2.0 V
PP
above and below the signal ground
voltage (V
DD
/2).
The output load resistance is a minimum of 1.2 k
W
.
During power saving or power down mode, the output of AOUT is at the voltage level of the
signal ground.
