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.

Audio VU Meter. Circuit : Matthew Hewson Email: [email protected] 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.

Lm324 Ic Vu Meter Circuit Diagram Circuit Diagram

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.

LED VU Meter

This 8 LED VU meter circuit can be used to display the variation of an audio signal in a group of 8 LEDs, behaving like a VU meter. We could use a specific integrated circuit used for VU meters, but we decided to use a readily available integrated circuit: The LM324 operational amplifier.

4QDTEC Audio LED VU meter

VU is an abbreviation for volume unit. Thus, a VU meter is a device for measuring the level of SOUND intensity with audio equipment, such as AMPLIFIERs and TAPE RECORDERs. Although the measurements indicated on such a meter are in DECIBELs, the zero level should not be confused with 0 dB, the THRESHOLD OF HEARING.

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.

1 simulate this circuit - Schematic created using CircuitLab I have made a LED VU Meter using LM3915 and added a low pass filter too. Then I've tried a basic op amp circuit using LM324 (inverting and non inverting) to amplify the LM3915's input, but it doesn't work. It only lights up the first led, it doesn't work like a VU meter should.
