Hi guys (correct me if im wrong anywhere in my method)
I am looking into the minimum CMR that is required in an Instrumentation Amplifier (IA) used to convert a differential signal (from the S250 strain gauge) to a single ended signal (ready to be ADC'd).
If the excitation voltage (Vexc)...
Hi all,
I have used a PICmicro (as mentioned earlier in the thread - wanted to concentrate on a particular aspect)
I have used the PICmicro I/O to source the power to several components in the circuit. I know that each I/O pin of the PIC16C62B is able to source 25 mA - but if i am powering the...
Hi all,
I have been trying to look for web pages which give information regarding the main types of microcontrollers that are available today i.e. Amtel, PICmicros etc and there advantages/disadvantages. Ive been sifting through many web pages all morning but somehow cant find that info!!!
Any...
Hi All
I have a technical question relating to the Wheatstone bridge for a medical kit.
Background
I am using an S250 Loadcell (strain gauge) which incorporates an inbuilt 4-wire closed Wheatstone bridge. I am applying an excitation voltage of 5V (+/- 0.1V) across the bridge (as supply rails...
Hi All,
I am new to this forum.
I have selected an SAR ADC for a piece of medical instrumentation. However, I wanted to know how I can select the most suitable resolution ADC. What are the steps in selecting the most suitable resolution e.g. 10 bit?, 12 bit? or 14 bit? or higher?
Does it...
