SA572NG

Audio Special Purpose Overview

The onsemi SA572NG is a dual-channel, high-performance analog compandor integrated circuit designed for dynamic range compression and expansion. It operates within a supply voltage range of 6V to 22V and features a typical dynamic range of 100dB (at 1kHz). The device functions reliably across an operating temperature range of -40°C to +85°C. Packaged in a 16-PDIP through-hole case, it serves as a specialized component for audio signal processing applications requiring precise level control.

Audio Special Purpose Feature Summary

• Dual-channel architecture for simultaneous audio channel processing
• High dynamic range specification of 100dB (typical)
• Wide supply voltage operation from 6V to 22V
• Through-hole mounting in a standard 16-pin DIP package

Audio Special Purpose Applications

• Consumer audio equipment
• Telecommunication systems
• Professional audio mixers

Audio Special Purpose Procurement Notes

Verify the specific ordering suffix 'NG' against official manufacturer documentation to confirm material composition or environmental compliance status, as datasheets may list generic variants like SA572N. Confirm current availability status, as older audio ICs may be subject to discontinuation notices. Ensure the 16-PDIP package dimensions match the target PCB footprint requirements before procurement.

Audio Special Purpose Selection Notes

Select this component when a dual-channel analog compandor with a 100dB dynamic range is required for consumer or telecom audio designs. Ensure the power supply rail accommodates the 6V to 22V input range. The through-hole 16-DIP package dictates the board layout strategy. Verify that the -40°C to +85°C operating temperature range meets the environmental constraints of the final assembly.
