for amplifying , use the NON INVERTING AMP, Select the gain to 50, to achieve this mark. But it must be taken care that , if the 2mV signal is induced with noises, then the same will also get amplified, so better to use a filter along with that. With the same Opamp, you can a make an active filter.
Re: How to design an OpAmp Circuit for pH Sensor which will be interfaced to PIC
While interfacing with the PH probes, the first thing we should take care of its impedance, usually its in 100s of Mohm range. So according to the pH of the solution, its act as battery terminal and generate a...
Re: I m stuck with this error for 2days..help
did you enable the Lcd in the library manager. ? If not tick the Lcd box in the library manager tab in the RHS toolbar
Thank you for the support,
I just tried by reducing the PWM frequency. Now its seems to the earlier 30% duty cycle margin is increased to 50% without heating. I believe its because of the Bootstrap capacitor's charging & discharging timings.
Yes the actual buck-boost circuit gives an...
Thank you for your replies...
When I gone through some documents , the buck boost topology is created with some different circuit. The inductor L is connected from High Side mosfet's Source to the GND. But its output is mentioned as inverting. And For the Non-Inverting type Buck-Boost...
Hi,
One doubt, whether this circuit is working ? In the circuit its seen that , the -ve line of the bridge is connected to the L-C-R junction, which is the out terminal of the buck conv. Its required to connect with the other side.
Hi,
I was just trying to implement a Buck-Boost converter with a driver method as shown in the image. Since the IR2110 have individual High side and low side driving, i actually
thought this will help to avoid the using discrete components. But now I came to realize that I was wrong !
The...
Yes 1% tolerance was applied. Its seems to be fine. Anyway in practical implementation some more changes can be expected, that's why I mentioned that.
Ofcourse its a fact !. Its really not need to have a 18bit ADC here. But I have some of them . (I can't use the uC's internal ADC here). Even...
HI All,
I need to implement a high side shut resistor based current sensing with a Differential ADC. Here the line consists of around 12VDC @ current varies from 1 to 10A. Eventhough the drop stands within the Differential i/p voltage limit(+/- 2.048V), its common mode voltage is higher...
Try the following LCD commands in the order (its in C, take the commands from it.)
LCD_command(0x38); // 8-bit, 2 Line, 5x7 Dots
LCD_command(0x38);
LCD_command(0x38);
LCD_command(0x08);
LCD_command(0x01); // Clear LCD
LCD_command(0x06); // entry mode , auto increment with no...
Hi all,
I got a SMPS power supply, used for the Server . Its model number is mentioned as Sunpower RPS2600(please the pics). I didn't find any relevant details regarding its pins. If anyone is familiar with this model, Please help me to figure out the pin details.
Thank you
Geo
Check the datasheet for the DTMF decoder IC MT8870. By interfacing the output pins of this IC to a microcontroller, you decode the DTMF tones and do the necessary job for your IVRS requirement.
