Integrated Circuit
9–Step LED Driver Circuit for Logarithmic Scale
Functions:
D Indication Way: Indicates input level in a series bar by 9 red or green LED’s
D Input Amp:
DC amp installed the aim of which can be varied by a peripheral resistor.
D Comparator Level: Designed with 3dB rate;
–18dB, –15dB, –12dB, –9dB, –6dB, –3dB, 0dB, +3dB, +6dB
D Supply Voltage: Wide recommended supply voltage: 5.5 to 16V At Vref2: 7 to 16V
D Reference Voltage: Vref (5V) pin can prepare another voltage regulator with added transistor
Applications:
D For AC Level Meter as VU Meter
D For DC Level Metetr as Signal Meter
Comparator Level: (TA =+ 25°C, VCC = 12V, Vrefl = 3V)
