BA682A中文资料LED level meter driver, 12–point, VU scale, dot or bar display数据手册ROHM规格书

描述 Description

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.●

特性 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

应用 Application

Level meters for all types of audio equipment applications
