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(3.5V~16V)
*Not necessary diode or transistor for ALC
*Minimum number of external parts required
