Single-Ended-to-Differential Conversion of a 4VP-P Input with Gain of AV = 2 to Drive an ADC for Applications Where
the Importance of High Input Impedance Justifies Some Degradation in Distortion, Noise, and DC Accuracy. Input Is
True High Impedance, However Common Mode Noise and Offset Are Present on the Output. Additionally, When the
Input Signal Exceeds 2.8VP-P, a Step in Input Offset Will Occur That Will Degrade Distortion Performance
