Lm3915 Circuit Diagram. The lm3915 block diagram consists of ten comparators on the inverse inputs of which an input signal is applied through a buffer operational amplifier and direct inputs are connected to the taps of the resistive voltage divider. Lm3914n will display an amplitude of a signal in linear form.
Lm3914n will display an amplitude of a signal in linear form. Which the external circuit is the same. The signal from buffer then goes to a group of 10 comparators.
The signal from buffer then goes to a group of 10 comparators.
The main of this circuit is lm3914n or lm3915. In this audio level indicator or sound level meter the lm3915 ic pi number 1 and 10 to 18 are directly connected to the led negative terminals. Lm3915 projects circuits 4 browse through a total of 4 lm3915 projects circuits. Which the external circuit is the same.
