Led Level Meter Driver, 12-point X 2 Channel, Vu Scale, Bar Display - Rohm

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. By ROHM Co. Ltd.
