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.
Applications
Level meters for VCRs, stereo cassette players, audio
amplifiers and karaoke equipment.
Features
1) Uses dynamic-drive system to display two 12-point
channels. 22-pin SOP and 22-pin shrink DIP pack-
ages.
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.
4) A mute function is provided, and muting can be ap-
plied externally.
5) Power on mute function.
