The MIC4478, MIC4479, and MIC4480 are low-side dual MOSFET drivers are designed to switch N-channel enhancement type MOSFETs from TTL-compatible control signals for low-side switch applications. The MIC4478 is dual non-inverting, the MIC4479 is dual inverting, and the MIC4480 is complimentary non-inverting and inverting. These drivers feature short delays and high peak currents to produce precise edges and rapid rise and fall times.The MIC4478/4479/4480 are powered from a +4.5V to +32V supply voltage. The on-state gate drive output voltage is approximately equal to the supply voltage (no internal regulators or clamps).In a low-side configuration, the drivers can control a MOSFET that switches any voltage up to the rating of the MOSFET. The MIC4478/4479/4480 are available in the 8-lead SOIC (ePAD and non-ePAD) package and are rated for the –40°C to +125°C ambient temperature range.

高通的QCC304x及后續(xù)的芯片支持HybridANC,包含F(xiàn)FMIC和FBMIC。其中FFMIC可以與2-CVC中的副MIC共用同一個(gè)MIC,可以是數(shù)字MIC或者模擬MIC。但是如果是模擬MIC的話,因?yàn)锳NC與CVC會(huì)共用FFMIC的模擬增益。
? 在很多應(yīng)用場(chǎng)合,要用到多MIC設(shè)計(jì),比如AI語(yǔ)音識(shí)別,就要用到多個(gè)硅麥的設(shè)計(jì),以提高語(yǔ)音識(shí)別的精準(zhǔn)度,本人曾做過(guò)兩個(gè)這樣的項(xiàng)目,下面分享下設(shè)計(jì)心得,看到這篇文章的朋友如果覺(jué)得有所幫助的話,記得
