SA572D

Audio Special Purpose Overview

The SA572D is a dual-channel, high-performance programmable analog compandor manufactured by onsemi. It operates within a supply voltage range of 6V to 22V and supports an analog interface. The device is housed in a 16-SOIC package (0.295", 7.50mm width) designed for surface-mount installation. It functions as a compression-expansion unit with a dynamic range specification of 110dB and maintains operational reliability across a temperature range of -40°C to 85°C.

Audio Special Purpose Feature Summary

• Dual-channel architecture allowing either channel to be used for dynamic range compression or expansion
• 110dB dynamic range specification
• Wide supply voltage operation from 6V to 22V
• 16-SOIC surface-mount packaging (7.50mm width)
• Operational temperature range: -40°C to 85°C

Audio Special Purpose Applications

• Consumer audio equipment
• Telecommunication systems

Audio Special Purpose Procurement Notes

The SA572D is classified as obsolete/discontinued by the manufacturer. A Product Change Notice (PCN) dated February 11, 2009, indicates end-of-life status. Availability is limited to secondary market distributors such as Rochester Electronics, LLC. Verification of part authenticity and condition is critical when sourcing from non-primary channels due to the end-of-life status.

Audio Special Purpose Selection Notes

Designers requiring this specific dual-channel compandor function must account for the component's discontinued status. Alternative solutions should be evaluated if long-term supply stability is required. Ensure that the 16-SOIC footprint and 6V-22V supply requirements align with the target system design constraints.

Audio Special Purpose Part Context

The SA572D belongs to the SA572 family of audio special purpose integrated circuits. It serves as a specialized component for dynamic range control in analog audio signal chains. The 'D' suffix denotes the specific 16-SOIC surface-mount package variant within the broader product line.
