BA6803S
The BA6803S is a two-channel, 16-point fluorescent display tube driver for VU-scale bar-level meters. It uses a dynamic-
drive system and has 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.
The grid output duty cycle is 1 / 8.
Applications
Level meters for all types of AV equipment
Features
1) Uses dynamic-drive system to display two 16-point
channels. 30-pin SDIP 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 typ.).
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.
Absolute maximum ratings (Ta = 25 C)
