Audio ICs
5-channel stereo graphic equalizer
BA3822LS / BA3822FS / BA3823LS / BA3824LS
The BA3822LS, BA3822FS, BA3823LS, and BA3824LS are monolithic, five-point stereo graphic equalizer ICs.
Each IC has two channels, and the five center frequencies for each channel are independently set using external capaci-
tors. These ICs feature a wide operating power supply voltage range (V
CC = 3.5V to 14V), and are available in compact
24-pin SZIP and SSOP packages, depending on the type. This makes them an ideal choice for home stereo systems,
radio cassette players, and car stereos.
The difference between the ICs is the amount of boost and cut control. Choose according to the requirements of your
application.
