REFERENCE VOLTAGE SOURCE
(PINS 9 AND 14)
Pin 9 is the reference voltage pin for the compressor and
pin 14 is the reference voltage pin for the expander. The
reference voltages are obtained from an internal band gap
reference and used as the bias source for each section.
SWITCH CIRCUIT (PINS 11, 12, and 13)
The compressor's and expander's mute pins and the through
pin (noise reduction is off) are pulled up by internal current
sources, therefore they do not need an external pull up.
Concerning the switching logic, refer to the table in the Test
Circuit section.

EXPANDER INPUT AMPLIFIER
The non-inverting and inverting input pins as well as the
output pins are available, and can be used as a buffer amp
or filter amp. A data signal can be obtained from the output
pin, without passing through the expander. The input level
and amplifier gain should be set to provide 180 mV(rms)
standard level at the data output pin (pin 17). The expander
input amplifier is not DC biased internally, therefore a bias
voltage from the expander's V
REF
pin (pin 14) should be
used. The maximum allowable load at the output pin is 10
