8.2.4 Limited Output, ADC Input Driver

Figure 8-12 shows a simple ADC driver that operates on a single supply, and gives excellent distortion performance. The limit voltages track the input range of the converter, completely protecting against input overdrive. The limiting voltages are set 100mV greater than or less than the corresponding reference voltage from the converter.
