The BA6810S is a two-channel, 12-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, allowing cost and space savings while improving reliability.

The grid output duty cycle is 1 / 8.

Features

1) Uses dynamic-drive system to display two 12-point channels. 30-pin SDIP package.

2) AC and DC inputs provided. Switching function allows two-mode display.

3) Upper 8 points have peak hold function in AC mode (two seconds Typ.).

4) Power-on mute function.

5) Forced-mute function.

6) Terminal for meter sensitivity adjustment provided (adjustment with one terminal is possible).

7) I2L injector current terminal provided.

8) Square root compression amplifier built in.

9) Dynamic-drive system reduces the power dissipation of the fluorescent display tube power supply.

Applications

Level meters for all types of AV equipment
