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

The display level range is 13mVrms to 327mVrms (Typ.), the 0dB level is 130mVrms (Typ.) and the VU display is -20dB to +8dB.

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

● Features

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 allowing different types of LEDs to be used in combination.

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 series, power dissipation is reduced.

● Applications

Level meters for all types of audio equipment applications
