LED level meter driver, 12–point,
VU scale, dot or bar display
BA682A
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.
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.
