The AN6888 is an IC driving 5 × 2-ch LED and is capable of logarithmic bar graph display for input signal.
Incorporating high gain rectification amp. enable to apply
VU/Signal meter widely. Because the output is the constant current pull-in type, the constant current value can
be variable by external resistance.
