PRODUCTION DATA
Using the equation for a non-inverting amplifier configuration ; G = 1+ R2/R1, set R1 to 10kΩ, and R2 to 99x the value of R1, which would be 990kΩ. Replacing the 990kΩ with a 1MΩ will result in a gain of 101, which is within the desired gain tolerance.
The gain-frequency characteristic of the amplifier and its feedback network must be such that oscillation does not occur. To meet this condition, the phase shift through amplifier and feedback network must never exceed 180° for any frequency where the gain of the amplifier and its feedback network is greater than unity. In practical applications, the phase shift should not approach 180° since this is the situation of conditional stability. Obviously the most critical case occurs when the attenuation of the feedback network is zero.
