1 / 12 page © Semiconductor Components Industries, LLC, 2006 March, 2006 − Rev. 2 1 Publication Order Number: SA572/D SA572 Programmable Analog Compandor The SA572 is a dual-channel, high-performance gain control circuit in which either channel may be used for dynamic range compression or expansion. Each channel has a full-wave rectifier to detect the average value of input signal, a linearized, temperature- compensated variable gain cell ( DG) and a dynamic time constant buffer. The buffer permits independent control of dynamic attack and recovery time with minimum external components and improved low frequency gain control ripple distortion over previous compandors. The SA572 is intended for noise reduction in high-performance audio systems. It can also be used in a wide range of communication systems and video recording applications. Features • Independent Control of Attack and Recovery Time • Improved Low Frequency Gain Control Ripple • Complementary Gain Compression and Expansion with External Op Amp • Wide Dynamic Range − Greater than 110 dB • Temperature-Compensated Gain Control • Low Distortion Gain Cell • Low Noise − 6.0 mV Typical • Wide Supply Voltage Range − 6.0 V-22 V • System Level Adjustable with External Components • Pb−Free Packages are Available* Applications • Dynamic Noise Reduction System • Voltage Control Amplifier • Stereo Expandor • Automatic Level Control • High-Level Limiter • Low-Level Noise Gate • State Variable Filter *For additional information on our Pb−Free strategy and soldering details, please download the ON Semiconductor Soldering and Mounting Techniques Reference Manual, SOLDERRM/D. http://onsemi.com See detailed ordering and shipping information in the package dimensions section on page 10 of this data sheet.
