AN6888

ICs for Display Driver AN6888 Dual 5-Dot LED Driver Circuit s Overview 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. 1 2 3 21.7±0.3 4 5 6 7 8 9 6.3±0.25 3.8±0.25 (3.45) 18 17 16 15 14 13 12 11 10 0.51min. 2.54 0.3 – 0.0 + 0.1 5 Unit : mm 0.5±0.1 1.2±0.25 VCC 11 12 13 14 15 s Features Wide range of operating voltage : VCC (opr.) = 5V ~ 16V Power consumption can be reduced due to series connection of LEDs Wide range of constant current : 5mA ~ 25mA Built-in high gain amp. : GV = 26dB typ. 3 ~15˚ 7.62±0.25 18-Lead DIP Package (DIP018-P-0300E) s Block Diagram – C1 GND 1 9 + R1 16 – – + + – – + + – – + Vi 17 + VREF Vi 2 + – + – – + + – – + + – 10 RA C1 + – 3 13 8 7 6 5 4 www.DataSheet4U.com R1 ...
