LA2284 LA2284A Datasheet

5-DOT DUAL LED LEVEL METER DRIVER


 
DESCRIPTION
 
     The UTC LA2284/A 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.



 
FEATURES
 
*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
*Not necessary diode or transistor for ALC
*Minimum number of external parts required
