•
•
Both amplifiers (A1, A2) have feedback loops individually closed with stable responses (overshoot negligible)
Acquisition time TA, estimated by:
•
•
•
LF156 develops full Sr output capability for VIN ≥ 1V
Addition of SW2 improves accuracy by putting the voltage drop across SW1 inside the feedback loop
Overall accuracy of system determined by the accuracy of both amplifiers, A1 and A2
