Thank you very very much Sir . I really appreciate your sense of understanding. I will make all the necessary adjustments in my design so as to make use of an external VRef. Once again thank you for taking the time to put me through. I really appreciate it. Best regards.
Thank you once again for the response. I really appreciate your sense of understanding. I am actually using the ADC of Atmel Attiny87 microcontroller for the analog to digital conversion. The analog signal input to the ADC has a range of 4mA to 20mA,this range corresponds to 50ºC to 400ºC(that...
Thank you all for taking the time to go through my post. I really appreciate your Kind gesture.Sir i would be very glad if somebody could try and explain this concept to me. Like klausST said above. I actually used a 250 Ohms resistor at the Input pin of my ADC circuit and i measured the current...
Good day to all,
Please i need your support . I am looking for an IC that i can use to design a DC Voltage to Analog current converter.The Analog current Signal should be in the range of 4mA to 20mA. I want to use the Analog current as an Input into to my Analog to Digital converter...
Thank you very much for taking the time to go through my post, I really appreciate your Kind gesture. I am actually using the ADC of a microcontroller to convert the analog Signal to digital signal, so i did not not use any Op Amp in my circuit. My plan is to now convert the digital Signal...
Good day to all,
Please i need your support on how i can scale an analog current Signal with a range of 4mA to 20mA into temperature range of 50°C to 400°C. The 4mA corresponds to 50°C while 20mA correspond to 400°C. I tried to do the scaling with the formular below, while the 4mA result(50°C )...
Thank you all for taking the time to go through my question, I really appreciate your sense of understanding. I made some adjustments to my block diagram based on the explaination giving by FvM. I would be glad if you could help me have a look at the new block diagram so as to confirm...
Good day to all,
Please i need your Support in helping me to confirm if the block diagram i attached to this thread is correct. I want to read an analog Signal from a sensor and convert it to a digital Signal with the help of an in-built ADC in a microcontroller. I am not sure if...
Good day to all,
Please I need help on how to get a stable 5V to my microcontroller. I want to convert the Output analog Signal from a sensor to digital Signal using the ADC peripheral in a microncontroller.According to the datasheet of the sensor,the Output voltage analog Signal has a...
Good day to all,
Please I need help on how to write the Clock Code for my Slave device. I understand that only the Master device can generate the clock signal while slave device will listen to the incoming signal however I do not know how to implement this concept in the slave program...
Dear Sir/Ma,
Please I need your Support.I am not too sure if this Kind of configuration is possible.I am trying to use the Usi-Spi of Attiny4313(as Master)to receive DATA from Attiny24A(Slave).I am using the GPIO PINs of Attiny24A to send the DATA to the Master.I have already tried this...
Good day to all,
Please I need your support and guide on how to solve this Problem.I am using Orcad Pcb Editor 16.0 for my circuit design.After completing the layout,i generated the Gerber files and sent it to the company that will produce the Board but the Company sent a message to me that...
Good day to all,
Please I Need your guide and support before buying this dimmable power supply:
https://www.osram.com/osram_com/prod...ent-dimmable/optotronic-intelligent/index.jsp
I have a PCB that has a cluster of 120 Leds on it with Series-Parallel connection.(A cluster is made of 5 Leds...
Good day to all,
Please I need your support and guide on how to get the required current to my circuit.The power supply I intend to use has a switching regulator (RT8289GSP ) with output voltage of 5V/5A(based on the current configuration of the switching regulator-application note from...
