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 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. s Features • Wide range of operating voltage : VCC (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. : GV = 26dB typ.
