Korg microKorg E.2.1 Error - No Sound, Output Thumps, Service Tests Fail Work Done So Far Power supply recap: Most electrolytic capacitors replaced with equivalents, A lot were out of spec. Power rails now measure stable (no voltage drops noted at any ic's) Service mode testing: Mode 1+3...

Hey, I´m currently trying to convert a 20kHz PWM Signal generated with an ESP32 to DC voltage. Goal is to control a hydraulic proportional flow control valve with a DRV103 solenoid Driver. The DRV103 needs an analog Input Signal from +2.2 - +5V to activate the Output. With the ESP I´m able to...

Hey all, I am looking for some design guidance on on DACs & I2C. I am designing a circuit which includes two DAC & Amplifier subcircuits, we can call it 5V_DAC and 24V_DAC. Both of them use the MCP4725AOT DAC which does not have an enable pin. They both rely on the SCL and SDA signals from an...

I'm designing an analog output that takes a 0-5volt from a DAC and uses an op amp to step it up to 0-10volt, then turns it into a 0-20ma signal with a XTR111 and can use a switch to output 0-10v or 0-20ma. I want to make sure everything looks good before I start my first prototype.

Hello, I'm looking for some advice on a project I'm doing and more specifically the best microcontroller to approach this. I've tried an approach already but reached a number of hurdles and need to return to square one. The project is a physical desktop intercom which takes only a power...

Hello everyone, I have been trying to understand fully the behaviour of the capacitor and over its two plates when exposed to sudden changes in voltage, and I divide my request for help into two questions: 1- How and why when we apply a sudden voltage over a capacitor C1_Plate_1, the C1_Plate2...

Can anyone please solve this problems ?

Hello! My plan is to create a circuit, which would effectively transfer 6 channels of analog 16-bit audio signal to the other side without loosing quality or inducing some kind of interference. Cable length would be around 5 meters. This circuit would be used in automotive to substitute 6 RCA...

Hello all, I have the attached datasheet for an audio D/A converter (CS43L22) which have stereo headphone out/line out. I couldn't understand fully the audio jack schematic in the typical connection diagram, specially the difference between the highlighted elements!? can someone explain the...

So here: I assume each transistor has some sort of parasitic capacitance and that adds up into the non inverting terminal of the op amp? Why do those parasitic capacitances appear and how can i reduce them? And in this case: These capacitances appear because of Q4/Q3... ? They depend on...

This is from a text book: I dont understand any of it

Hi, I am looking for Industrial Grade Wireless Digital-to-Analog Converters (DACs). These DACs should be capable of receiving and accepting wireless digital transmission from industrial grade wireless vibration sensors, convert it into its corresponding analog/voltage signal, and send this...

This may be novice question. I am understanding SAR ADC specification for modeling perspective. In the mean time I was following analog devices Driving SAR ADC. In general what the necessity for a driver when it matches T acq and T cov of the selected ADC datasheet? What else test situation or...

Hello, I'm currently working on a project that requires the use of an MCP475 DAC. Currently, it is being powered from the 3.3V source from on a Raspberry Pi and hence works in the range of 0V to 3.3V. I need it to work in the range of -3.3V to +3.3V. By reading the spec sheets I found that I...
