Audio ICs  
LED level meter driver, 12-point   2  
channel, VU scale, bar display  
BA6820F / BA6822S / BA6822F  
The BA6820F, BA6822S and BA6822F are two-channel, 12-point LED drivers for VU-scale bar-level meters.  
The ICs are available in 22-pin SOP (BA6820F and BA6822F) and 22-pin shrink-DIP (BA6822S) packages, and use  
a dynamic-drive system that can drive two 12-point displays. The ICs have independent AC and DC inputs, and the AC  
input mode has a peak hold circuit (with cancel function). The ICs also feature a power-on mute, so steps to prevent  
erroneous LED lighting at power on are not required.  
The input resistance of the AC inputs is 3k(Typ.) for the BA6820F and 0.3k(Typ.) for the BA6822S/F.  
FApplications  
Level meters for VCRs, stereo cassette players, audio  
amplifiers and karaoke equipment.  
FFeatures  
1) Uses dynamic-drive system to display two 12-point  
channels. 22-pin SOP and 22-pin shrink DIP pack-  
ages.  
4) A mute function is provided, and muting can be ap-  
plied externally.  
5) Power on mute function.  
2) Independent AC and DC inputs provided (one input  
displays one channel). Switching function allows  
two-mode display.  
3) Upper 8 points have peak hold function in AC mode  
(two seconds). A peak-hold cancel function is also  
provided.
