| 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 capacitors. These ICs feature a wide operating power supply voltage range (VCC = 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. FApplications Five-point stereo graphic equalizer for home and car stereo systems. FFeatures 1) Allows construction of a five-point stereo graphic equalizer with a single IC. 2) Wide operating power supply voltage range (VCC = 3.5V to 14V). 3) Low current dissipation (IQ = 7mA). 4) Available in compact SZIP / SSOP-A24 packages. FAbsolute maximum ratings (Ta = 25_C) FRecommended operating conditions (Ta = 25_C) 550 Audio ICs BA3822LS / BA3822FS / BA3823LS / BA3824LS FElectrical characteristics BA3822LS and BA3822FS (unless otherwise noted, Ta = 25_C, VCC = 8V, VIN = 100mVrms (1kHz), RL = 20k, and F = FLAT) BA3823LS (unless otherwise noted, Ta = 25_C, VCC = 8V, VIN = 100mVrms (1kHz), RL = 20k, and F = FLAT) BA3824LS (unless otherwise noted, Ta = 25_C, VCC = 8V, VIN = 100mVrms (1kHz), RL = 20k, and F = FLAT) 551 Audio ICs BA3822LS / BA3822FS / BA3823LS / BA3824LS FDifferences between the BA3822LS, BA3822FS, BA3823LS and BA3824LS FControl range gain FExternal components As the ICs have different control range gain, the external component values are different for the same center frequencies. FRipple rejection The BA3823LS circuit design has excellent ripple rejection, and the external ripple filter can be omitted.
