Hi,
Sorry for delayed reply.
Please ignore about Wheatstone bridge and resistance values of sensor for now.
I have given direct voltage to input terminals through two separate voltage sources instead of bridge.
The configuration is
MAX 4208 is powered through 5V DC single supply.
Input...
Hi Klaus,
L1 and L2 are sensors whose resistance is 3 ohm each. When the parameter (physical entity which is to be measured) is detected L2 resistance decreases by some value and bridge will be imbalanced. That difference signal is to be amplified by MAX4208.
Whatever values mentioned in...
Hi,
I am using MAX4208 in Wheatstone bridge configuration as per attached image.
The supply voltage for bridge is 2.7 V and MAX4208 voltage is 5V. The resistance of Detector and Compensator is 3 ohm each and 1 k are on other side of bridge.
When Grounds of 2.7 V and 5 V are isolated (Driving...
Hi,
I a using PIC18F87K90 microcontroller. The program code is written already and working properly on PIC18F87K90 I/PT. But when I am using same code on PIC18F87K90 I/PTRSL it is not working. Can anyone please guide me about the difference between PIC18F87K90 I/PT and PIC18F87K90 I/PTRSL...
It will be great if anyone suggest how do I reduce load current.
Suggest some ultra low power consuming components like LCD,LED's, Buzzer, Vibrator if available.
Hi,
Greetings of the day!!!
I have to design portable battery operated device. Battery is from Tadiran make TLL 5902. The device containing micro controller,sensor, LED's, Buzzer and vibrator and LCD display.
The battery should work for 20,000 hours is the major requirement. To achieve this...
Hi,
Greetings of the day!!
I am using MCP 3204 ADC interfaced with PIC18F4520. The reference voltage of MCP 3204 is from voltage divider network of resistor and set to 500mV. Potentiometer value is 1K and resistor of 1.2K.
Input signal range is 0-500mV.
Even though the input signal and...
Hi,
I am sorry for using wrong term. I mean to say multidrop connection. The problem was occurring because of improper voltage (reverse voltage i.e. VCC is connected to GND and vice versa) to bias resistors.
Thanks for your support!!

Hi,
I have a monitor which is programmed as modbus slave (RTU ). When I am connecting single device and checking the RS485 communication using Modbus poll and RS232 to RS 485 converter, it works fine. But when I connect another similar device in loop at that time it gives insufficient data byte...
Hi,
Thanks for suggestions!!
I have re installed everything (CCS compiler as well as MPLAB IDE) and it starts working again!! Surprised Surprised
Thanks a lot for your help!!
Hi,
I am using MPLAB IDE version 8.60 and CCS compiler for programming of microcontroller PIC18F4520. I have working code which I am using since last 1 year. But suddenly I am facing a weird problem from couple of days. When I am reprogramming the micro controller it is not functioning as...
Thanks for your prompt reply.
The excessive current consumption is due to capacitors C9 to C12 which are connected at the output of the op amp. Now removed that capacitors and the consumption is below 3 mA.
Thanks again for your help!!!!

Paddy
Hi,
I am using XTR 117 for two wire transmitter design. Please refer attached schematic.
Everything working fine except current consumption of the circuit. The total current consumed by circuit is around 7mA. Because of that I am not able to achieve the 4mA output.
I have implemented same...
Hi,
Greetings of the day!!!
I have got a display board which has 3 common anode 7 segment displays, 7 individual LED's and 4 switches.
Segments are driven by using port 0 of P89V51RD2 micro controller (through 74HCT574 latch IC). The common terminals (COM1 to COM4 as indicated in schematic)...
Hi,
I am using INA 326 instrumentation amplifier. I have connected it in bridge arrangement as shown in datasheet. But it is not working.
I have checked it on TINA simulator where it works fine. But when I am testing it practically there is no output.
I have attached circuit and pics of my...
