Vumètre 02 / Vu meter 02 LM324
Description: This circuit uses two quad op-amps to form an eight LED audio level meter. The op-amp used in this particular circuit is the LM324. It is a popular IC and should be available from many parts stores. Notes The 1K resistors in the circuit are essential so that the LED's turn on at different audio levels.

The VU meter is a circuit for an indicator of the audio signal strength. The VU meter circuit is usually applied to an amplifier circuit so that the level of audio power can be determined by certain parameter settings which will be displayed in the form of light from the LED.

Internal circuit of the LM3914, with connections for making a 10-LED 0-1.2V linear meter with dot- or bar-graph display. FIGURE 4. Threshold-point values of the LM3914/15/16 range of ICs when designed to drive 10 LEDs at a full-scale sensitivity of 10V. Thus, the LM3914 is a linearly-scaled unit, specifically intended for use in LED voltmeter.

The VU meter is calibrated in volume units that are numerically equal to the number of decibels above the reference level. The circuit is conventional To turn on the LEDs at different audio levels, the 1K ohm resistor is necessary because higher values might cause some LEDs not to function properly even if LED has very low internal resistance.

Re: Help in designing a VU meter circuit w/ an electret mic. There wont be a speaker. it will just measure how noisy the room is or see how loud the music in the background is played. Get rid of the LM386 and humongous coupling capacitor and replace with another pair of LM358 stages - probably a gain of 50-100 will be sufficient (so each stage.

The exceptions are LM2902 and LM2904 devices having a "V" in the suffix, which denotes maximum voltage up to 32 V. Two examples are LM2902KAVQDR and LM2904AVQDR. All devices with a "B" in the suffix have a maximum supply voltage rated at 36 V; examples are LM358BIDR, LM2904BAIDR, LM324BIPWR, and. LM2902BIPWR.
