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 BA682...
