Input Buffer and Protection for ADC Driver

Section 9.2.1.1 shows the OPA2206 configured as an input buffer for an ADC driver using the THP210. The high dc precision and low noise of the OPA2206 make this device an excellent choice for precision signal chain conditioning. The low input bias of the amplifier minimizes dc errors created for higher output impedance sensors. The integrated input overvoltage protection prevents damage to the signal chain due to an input fault condition where the signal exceeds the supply range of the OPA2206, or if the inputs are shorted to a higher supply rail. For more information on designing a precision ADC driver,see https://www.ti.com/product/THP210.
