MAX9814具有自動增益控制(AGC)和低噪音麥克風偏置,

器具具有低噪音前端放大器,可變增益放大器(VGA),輸出放大器,麥克風偏置電壓發生器和AGC控制電路.

低噪音前置放大器具有12Db固定增益:VGA增益根據輸出電壓和AGC門限在20dB和0dB間自動調節,在未壓縮的情況下,放大器的級聯增益為40dB或50dB或60dB.

輸出放大器增益由一個三態數字輸出編程.AGC門限由一個外部電組分壓器控制.動作/釋放時間由單個電榮編程, 動作/釋放時間由一個三態數字輸入設置,AGC保持時間固定為30ms.低噪音麥克風偏置電壓發生器可為絕大部分駐級體麥克風提供偏置,MAX9814提供節省空間的14引腳TDFN封裝,該器件額定工作於-40℃至+85℃擴展級溫度範圍
