I am using an IR transceiver in my design.This IC is working at 3.3V supply.This IC need not be on always so I decided to give a control to it's shut down pin (Pin no 5,Shutdown Input. Active low).A transistor switch is used for this purpose.When the switch is ON the transceiver will be active...
Hello!
I have a PCB that uses STM32U575 MCU and it has 3 sensors shown in the image connected to it through I2C bus. Using internal ADC of the MCU I want to also read the analog data that is coming from the bus. Is there a way to do it? Maybe there is a example or a reference project which I...
Hello everyone! I have a task to choose ADC that will have at least 10 MSPS sampling rate and will be able to connect to STM32U575 directly. I very new with this topic, was searching through and found several ones that look like they might work.
Wanted to ask if someone can provide a feedback...
Hi.
Im currently designing a three leg shunt circuit. Im reading every shunt voltages using INA180A1 and output of the current sense amplifiers connected to the mcu. Mcu has internal overcurrent and short protection but system is very critical that shouldnt leave MCU alone for this purpose.
So...
Hey,
I'm not someone who is technically minded but I would like to build a passive "boost" for my guitar (increase signal with no batteries). I think I can do it with just the signal from the guitar amp. I know that Yamaha has made this work with a transformer. Is there any reason that a...
hello!
I was wondering if anyone could take a look at my circuit for my second version of my "precision" current sensor, specifically the analog section. (TL/DR Last Paragraph). my first version, discussed , was a overall failure, although I did learn quite Abit from that so it wasn't a total...
Research the ability of PLC's to communicate via 4-20mA and 0-10volts between the laboratory devices and the PLC
This would include how to communicate between these devices using an analog device that has 0-10 volts and converts to 4-20mA.
Hello, i'm new in electronic and i plan to make discrete bcd counter with T flip flop. Before i make it in real, i tried to make it in pspice. But when i pspice it, i found that second flip flop (which count as 2) does not reset when it is 10s (When it counts 1010) and because of it, reset...
Hello,
I have to make a control system that mantains constant speed of a small car prototype using a DC gearmotor regardless of external disturbances such as slopes (small slopes).
For the development of this project I thought that a posible solution could be a control system consisting of a...
Recently i started a project: trying to build my own function generator.
The most important reason for me doing this project is learning more about oscillators and their limits and possibilities.
So far i found a few designs such as the colpitts oscillator and the wien bridge oscillator.
The...
Hello everybody
i am new to analog design and i was assigned to do an analog design to sensor interfaces(LVDT , 4-20mA , differential 485) . the problem i am facin g right know is that i don't know exactly from where to start, (for example i don't know if i need a filter or not, and if i need...
Hi there, I could use a hand getting my head around a design for a single ended signal to differential input&output amplifier.
I'm using an AC current sensor (LTSR-6NP, **broken link removed**) which gives a single ended voltage output referenced to ground with the zero current point at mid...
Hello good people,
I need help. I'm posting a schematic of an ultra low noise amplifier. It is to be powered by batteries. For that reason, I need a stable DC solution in the place of R4 resistor. I was proposed to achieve that by using another JFET and an integrator circuit, but I am not...
I want to design an Analog Signal (0 to 10V DC) Generator. I am new to circuit design. I need help to design and manufacture this device. It will be very helpful if you can point me in the right direction.
I tested this circuit with a Arduino Mega board and generated upto 5V, but the resolution...
Hi, i'm using a PIC32 development board "Pinguino-OTG":
The microcontroller used in the board is a pic32mx440f256h.
I've tried several types of configuration codes and read functions. No matter what, i can't read the AN11 port (of the pic) which is connected to the AN6 pinheader on the board...
Hi all,
I'm working on an audio circuit that is really space limited. I purchased miniature 12MM 8 ohm speakers from "no name" brand from aliexpress, these speakers don't have a datasheet.
When I activated the circuit the sound is really low- even though the voltage on the speaker is 2V~3V.
I...
