LINEAR INTEGRATED CIRCUIT

5-DOT DUAL LED LEVEL METER

DRIVER

DESCRIPTION

The Contek LA2284 is a monolithic integrated circuit designed

for 5-dot LED level meter drivers with a built-in rectifying

amplifier. It is suitable for AC/DC level meters such as VU

meters or signal meters.

FEATURE

*High gain rectifying amplifier included (Gv=26dB)

*Low radiation noise when LED turns on

*Logarithmic indicator for 5-dot LED of bar type

*Constant current output(15mA)

*Wide operating supply voltage(3.5V ~ 16V)

*Not necessary diode or transistor for ALC

*Minimum number of external parts required
