| n overview the AN6888 is an ic driving 5 2-ch led and is capa- ble 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 con- stant current pull-in type, the constant current value can be variable by external resistance. n features ? wide range of operating voltage : v cc (opr.) = 5v ~ 16v ? power consumption can be reduced due to series con- nection of leds ? wide range of constant current : 5ma ~ 25ma ? built-in high gain amp. : g v = 26db typ. ics for display driver AN6888 dual 5-dot led driver circuit 1 2 3 4 5 6 7 8 3 ~15? 7.62 0.25 0.3 + 0.1 ?0.05 3.8 0.25 (3.45) 0.51min. 2.54 1.2 0.25 0.5 0.1 unit : mm 6.3 0.25 18 17 16 15 14 13 12 11 21.7 0.3 9 10 18-lead dip package (dip018-p-0300e) n block diagram + + + + + + + + + + + + v ref v i v i r a c 1 r 1 r 1 c 1 gnd v cc 1 9 16 11 12 13 14 15 4 5 6 7 8 13 3 10 2 17 + +
