FAN3852 集成了预放大器、LDO 和 ADC,会将驻极体电容式麦克风 (ECM) 输出转换为数字脉冲密度调制 (PDM) 数据流。该预放大器从 ECM 接受模拟信号,驱动过采样 sigma delta 模拟-数字转换器 (ADC),然后输出 PDM 数据。该 PDM 数字音频具有噪声抑制优势,还可以与移动电话听筒处理器进行轻松接口。FAN3852 具有集成式 LDO,从高达 3.63V 的系统电源轨供电,功耗仅为 0.85mW,在电源关闭模式下则不到 20µW。

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.)
