5-Dot LED Driver Circuit
Description
The AN6884 is a monolithic integrated circuit driving 5-LED and is capable of logarithmic (dB) bar graph display for input signal. Incorporating high gain rectification amp. enable to apply AC (UV meter, etc.) / DC (signal meter, etc.) level meter widely.
Features
• Wide range of operating voltage: Vcc• Constant current output: Iled = 15mA
• Built-in high gain amp.: Gv = 26dB typ.
• Low noise when LED ON
• 5-dot LED bar logarithmic response: -10, -5, 0,3, 6dB
• Fewer external components
