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 3kΩ (Typ.) for the BA6820F and 0.3kΩ (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.
