we are using ADXL 203 ... output is in 100 to 200 millivolts . how to amplify this millivolts output to volts .
opamp ma 741 with high gain didn't respond to accelerometer output. so please help us to ampify accelerometer output...
It's hard to solve an ill-defined problem......
What g range?
What supply voltage(s) are available?
What overall system accuracy at room temperature do you need? (741 is not a precision op amp.....)
What accuracy over temperature?
What temperature range?
Do you want to breadboard/hack one or two systems or build thousands per week? (Makes a difference, e.g. for one system
you can hand select resistors or turn a pot. You don't want pots in a production line.)
