AN6888 Dual 5-Dot LED Driver Circuit

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 variabl.

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
