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.
FApplications
Level meters for all types of AV equipment
FFeatures
1) Uses dynamic-drive system to display two 16-point
channels. 28-pin SOP package.
2) AC and DC inputs provided. Switching function al-
lows two-mode display.
3) Upper 12 points have peak hold function in AC mode
(two seconds).
4) Power-on mute function.
5) Dynamic-drive system reduces the power dissipa-
tion of the fluorescent display tube power supply.
6) Square root compression amplifier built in.
