Audio ICs

LED level meter driver, 12–point,

VU scale, dot or bar display

BA682A

The BA682A is a monolithic IC for LED level meter applications.

+8dB.

The constant current outputs can be set using external components allowing use of different color LEDs in various com-

binations.

FApplications

Level meters for all types of audio equipment applications

FFeatures

1) 12-point VU display meter driver for bar / dot displays.

2) Fixed-current outputs that can directly drive LEDs.

3) Output current can be set using external resistors al-

lowing different types of LEDs to be used in combina-

tion.

4) Built-in half-wave rectifier amplifier.

5) LED on and off timing can be set using an external

capacitor and resistor.

6) With bar-type display, by connecting four LEDs in se-

ries, power dissipation is reduced.
