DESCRIPTION

· The SA571 is a low-cost, dual gain control circuit suitable for dynamic range compression or expansion.

· It features a full-wave rectifier, a temperature-compensated variable gain cell, and an operational amplifier per channel.

· Ideal for cellular radio, modems, telephone, and satellite audio systems.

FEATURES

· Integrates both compressor and expandor functions in a single IC.

· Offers a dynamic range exceeding 110 dB.

· Operates at voltages as low as 6.0 VDC.

· System levels are adjustable using external components.

· Distortion can be trimmed out.

· Supports dynamic noise reduction systems and includes a voltage-controlled amplifier.

· Available in Pb-Free packages.

APPLICATIONS

· Used in cellular radio systems.

· Functions as a high-level limiter and low-level expandor (noise gate).

· Suitable for dynamic filters and CD players.
