ANALOG_IN7+ is a input signal with +4 to +6V range. how this circuit is working?
is there any signal conditioning?
OP200 is using in this circuit.
Your circuit will work as a 2-stage amplifier with a overall gain of 4.33.
Your 1st stage will work as an inverting amplifier with the gain equation:
You 2nd stage is a summing amplifier whose output voltage is:
I suggest you to use a lower value of R1 and R2 to your circuit to avoid instability. A few kiloohms will do.May I ask what your application is and why did you chose OP200?
i am using this circuit in military product where ANALOG_IN7+ is a input signal with +4 to +6V range and AnalogIN7+ is output signal then this output signal gives to multiplexer . multiplexer is 16 to 1 configuration and after multiplexing the multiplexer out gives to ADC.
