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 V
D Reference Voltage: V

(5V) pin can prepare another voltage regulator with added transistor
