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 components are required.

Features
1) Uses dynamic-drive system to display two 16-point channels. 28-pin SOP package.
2) AC and DC inputs provided. Switching function allows 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 dissipation of the fluorescent display tube power supply.
6) Square root compression amplifier built in

Applications
    Level meters for all types of AV equipment
