A simple passive logarithmic VU meter A simple circuit. The basic idea is to use the logarithmic characteristic of diodes to obtain a logarithmic response of an electromechanical microammeter. The circuit is shown below and is really very simple. It's based on a standard 200 μA microammeter which is very very common for this kind of applications. LED VU Meter Circuit Diagram using LM3914 and LM358 The circuit diagram of the VU meter is show in below figure, Working of VU meter Circuit is simple; at first MIC picks up the sound and converts it into voltages levels linear to the intensity of sound. So for a higher sound we will have higher value and lower value for a lower sound. 5 LED VU meter circuit diagram using KA2284 | CircuitsTune The KA2284, KA2285 are monolithic integrated circuit. It is a logarithmic display driver IC. And it is Bar type display driver using 5 Dot LED. The KA2284 KA2285 has a wide range supply voltage capacity of 3.5V 16V, but we recommend to use about a 12VDC power supply. AC signal Meter or DC Level meter. Logarithmic VU Meter Driver WSEAS logarithmic driver . At the input of the circuit, there is an input buffer that accommodates this circuit to preceding circuits in terms of the voltage level and the impedance of the signal. As there are two rectifiers employed in the circuit in order to improve the symmetry of either positive or the negative half wave of the A simple passive logarithmic VU meter : Repository circuits Non professional audio amplifiers often have simple (and useless) VU meters. For example, the circuit diagram shown in the figure below was found in my stereo set (rated 80WRMS on 8 ©) and is composed by a diode rectifier (actually a voltage doubler composed by C1, D1 and D2), a filter... Tutorial – LM3915 Logarithmic Dot Bar Display Driver IC ... The LM3915 offers a simple way to display a logarithmic voltage level using one or more groups of ten LEDs with a minimum of fuss. If you’re wanting to make a VU meter, you should use the LM3916 which we will cover in the final instalment of this trilogy. Audio VU meter Schematics wiring diagram circuits schema ... VU Meter 1 with transistor. VU Meter 2 with LM3915 LM3916 [19 Led] s chematics wiring diagram circuits schema electronic projects shema. VU Meter 3 with LM3915 [10 Led] S chematics wiring diagram circuits schema electronic projects. VU Meter 4 with LM3915 [10 Led] for Power Amp. Build an Analogue VU Meter with a normal Voltmeter Page 1 Re: Build an Analogue VU Meter with a normal Voltmeter. The supply voltage is low enough (regulated at 5V) that the reverse bias emitter base voltage rating on the transistor (6V) is never exceeded. The output is linear. It drives an LM3915 bar graph LED driver that has logarithmic levels. The LM3915 has a range of 30dB. HELP! Vu meter with LM393 | Electronics Forum (Circuits ... Hi! I'm new here and i need a little help with a project. I need a circuit diagram of a VU meter, using this components ; x4 LM393 , x10 5k and x10 10k resistors, x8 LEDs yellow and a 9V battery , 1 condeser microphone with 2 terminal VU meter circuit Stereo 20 LED with PCB | ElecCircuit Figure 1 Electronic VU meter circuit diagram by LM3914 and LM3915 The main in working of this circuit is LM3914N or IC LM3915 N as suitable for your working. Which the external circuit is the same. vu meter circuit Page 2 : Meter Counter Circuits :: Next.gr VU Meter Circuits. This circuit is based on LM3915 IC and uses the logarithmic version. This circuit is using a single IC and a few discrete components. The extra diode (D3) is included to ensure that the DC to the LEDs is almost unfiltered. C1 is inclu. Driving VU and other AC Meters Simple High Performance ... Conventional VU Meter Drive Circuit. The input is buffered U1 and fed into the germanium rectifier and meter via the standard 3.6kΩ resistor. R1 and R2 form a variable attenuator at the input with a range of 0dB to 6dB to allow a generous range of adjustment to compensate for any meter tolerances. VU Meter | Circuit Diagram The figure below shows a schematic diagram of a VU meter circuit. A VU (Volume Unit) meter is a very useful device to show the audio level in audio devices from which a user can maintain a certain audio level and get rid of overloading the output.
