概览

SA572 扩展器是一款双沟道、高性能增益控制电路，其中的每个沟道均可用于动态范围压缩或扩展。每个沟道均具有检测信号平均值的全波形整流器，线性化温度补偿可变增益单元 (DELTAG) 和动态时间恒定缓冲器。该缓冲器允许对动态攻击和恢复时间进行独立控制，且外部组件数量极少，比上一代扩展器改善了低频率增益控制波纹失真。SA572 适用于高性能音频系统中的噪音减少。它还可用于多种通信系统和视频录制应用。

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
