APPLICATION INFORMATION (CONT.)
BUFFER AMPLIFIER
Up to a third order LPF (for example, a splatter filter) can be
constructed using this amplifier. The maximum load at the
output pin is 10 k
. The non-inverting input of the amplifier
is not biased internally, therefore an external bias is needed
(for example Pin 3 V
) whenever this pin is not direct-
coupled from the compressor output pin (pin 3).

COMPRESSOR DATA INPUT
An inverting amplifier is used at the DATA input. The
internal input resistors are 100 k
, and the DC bias (V
REF
)
is about 1.5 V. The maximum load at the output pin is 10 k
.

COMPRESSOR SUMMING AMPLIFIER
The compressor summing amplifier (SUM AMP) must have
unity DC gain and the AC open loop gain is high. Since the
feedback resistors are internal to the device, only one
external capacitor is needed between pin 5 and GND. The
cutoff frequency is determined by the external capacitor
and the internal resistors.
RECTIFIER

TO GAIN CELL
RECTIFIER
The rectifier's smoothing capacitor pins (6 & 18), determine
the smoothing characteristics and the time constants of the
compressor and the expander. The time constant is deter-
mined by the external capacitor value and the internal 10
k
resistance.
