BA6800AF
The BA6800AF is a two-channel, 16-point fluorescent display tube driver for VU-scale bar-level meters.
It uses a dynamic-drive system and is provided with both AC and DC inputs. The AC input mode has a peak hold circuit.
The IC features a power-on mute, and the output block can directly drive fluorescent display tubes, so few external com-
ponents are required.
