PIN FUNCTION DESCRIPTION
Description
Connect to a clean power supply ground.
Output of the compressor section.
Compressor input. The input impedance is nominally 10 kΩ. Nominal signal range is
1.0 mVrms to 1.0 Vrms in normal mode, and up to 0.8 Vrms in passthrough mode.
Must be capacitor coupled to the signal source.
A logic high mutes the compressor. A logic low permits normal operation and passthrough.
Connect an external capacitor to filter the full wave rectifier’s output.
This capacitor affects attack and decay times, and low frequency accuracy.
Inverting input (7) and output (6) of an op amp internally referenced to Vb.
A logic high sets the gain of both expander and compressor to ≈ 0 dB, independent of
input level.
Inverting input (9) and output (10) of an op amp internally referenced to Vb.
Connect an external capacitor to filter the full wave rectifier’s output.
This capacitor affects attack and decay times, and low frequency accuracy.
A logic high mutes the expander. A logic low permits normal operation and passthrough.
This pin is not internally connected to anything.
Expander input. The input impedance is nominally 10.9 kΩ. Nominal signal range is
10 mVrms to 316 mVrms in normal mode, and up to 1.0 Vrms in passthrough mode.
Must be capacitor coupled to the signal source.
Output of the expander section.
Power supply. Connect to a power supply voltage in the range of 3.0 V to 7.0 V.
Bypass capacitor should be provided at this pin.
