vu meter

5 LED VU Meter project is based on LB1403/CH1403 IC from SANYO, which will indicates the volume level of the audio signal it senses. Features Power supply : 6 to 12 VDC @ 90 mA Lighting levels remain stable to line regulation because of on-chip voltage reference LED’s are driven by a constant...

This is a simple circuit diagram of 5-LED audio VU meter using IC KA2284/KA2285. The KA2284, KA2285 are monolithic integrated circuit. It is a logarithmic display driver IC. And it is Bar type display driver using 5-Dot LED. The KA2284/KA2285 has a wide range supply voltage capacity of 3.5V-16V...
