Functions:
• Indication Way: Indicates input level in a series bar by 9 red or green LED’s
• Input Amp: DC amp installed the aim of which can be varied by a peripheral resistor.
• Comparator Level: Designed with 3dB rate;
                           –18dB, –15dB, –12dB, –9dB, –6dB, –3dB, 0dB, +3dB, +6dB
• Supply Voltage: Wide recommended supply voltage: 5.5 to 16V At Vref2: 7 to 16V
• Reference Voltage: Vref (5V) pin can prepare another voltage regulator with added transistor

APPLICATIONs:
• For AC Level Meter as VU Meter
• For DC Level Metetr as Signal Meter
