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.

Features

1) Uses dynamic-drive system to display two 16-point channels. 30-pin SDIP 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 typ.).

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
