From input voltage noise RMS, we can calculate the final result, the input voltage noise peak to peak. Sign up Already a member?

So, the next step is considering the best amplifier from low noise operational amplifier family. Because we only using low resistance value on the both schematic, we only considering input voltage noise and neglected the input datashset noise of the amplifier [1].

Referring to Figure 1, OPA has 1. A project log for The Low Voltage Translator.

To choose the best amplifier for this purposes, we need to know the priority of the amplifier specification needed. Compared to the V4 SS op-amp, the V5 requires less voltage and current. Therefore, in 2nd version amplifier 3 op amp on the first stage is parallel to reduce voltage noise datasgeet the first stage of the amplifier.

Yes, delete it Cancel.

Since 1st version amplifier containing 4 parallel op-amps and 2nd version amplifier containing 3 parallel op-amps, so the 1st version winning the parallel effect for reducing noise. Every Supreme Sound Op-Amp in the world right now, be they V1 or V5 is covered by our lifetime warranty, something, no other op-amp manufacturer dares to offer. The Low Voltage Translator wants to detect small signal until 10 uV.

Our Supreme Sound Op-Amp, however, is specifically designed to optimize audio performance. The multiple stage configuration amplifier like in the 2nd version enabling to apply higher order filter than in the single stage amplifier configuration like in 1st version. Take note of the model number of the op-amp highlighted in yellow Take note of the pin-1 indicator with a half-cut circle highlighted in blue Determine if you need a dual-SS op-amp or a single-SS op-amp The SS Opamp is directly replaceable with the following opamps Dual Op-amps: We also neglect the current noise density of amplifier because we will use relative low resistance value of the resistors in the design [3].


The Low Voltage Translator translates low voltage into your multimeter or oscilloscope voltage range. Reference [1] Jones, David L. In the next project log, we will propose the design schematic and calculating input voltage noise peak to peak to meet the specification of The Low Voltage Translator.

This is the figure of OPA voltage noise density referring to its datasheet [2]. Since we want to detect 10uV, the nV is about 2.

Order your V5 Op-amp today. We need to divide those value with the gain of each amplifier to get voltage noise input in RMS. This is often overlooked in audio design where general-purpose IC-based op-amps are widely used.

Supreme Sound Opamp V5

Sign up Already a member? I have discussed with some expert about the best low noise op-amp used for this purposes and they suggest me the OPA Noise voltage input density of JRC from its datasheet Figure 4.

OPA input voltage noise density. The higher order low pass filter can reduced noise than lower order filter because the noise voltage in input op amp is white and can be reduced with more narrow bandwidth [3]. Is it an 8-pin IC chip like the one below highlighted in red? We use the best components and make them perform even better with painstaking selection and meticulous component matching.

So, the 2nd version winning the filter effect for reducing noise with the 3rd order low pass filter. Identify the op-amp inside your component. Yes, delete it Cancel. This is the figure of Dafasheet voltage noise density referring to its datasheet [4].

The total Gain in the 1st version amplifier is and the 2nd version is The Low Voltage Translator translates low voltage into your multimeter or oscilloscope voltage range.

In multiple stage amplifier configuration, the first stage of the amplifier add noise more significantly [3].

That means peak performance can be reached using mrc4580 power. The 2nd version amplifier is winning because of combining all method to reducing noise.

Please note that not following the first 2 steps above will certainly destroy the SS Op-amp, such jrc45800 will not be covered by our warranty.
