6.3.6 Driving Analog-to-Digital Converters

The OPAx354-Q1 family of op-amps offers a 60ns settling time to 0.01%, which makes the devices a viable option for driving high- and medium-speed sampling ADCs and reference circuits. The OPAx354-Q1 family of devices provides an effective means of buffering the input capacitance and resulting charge injection of the ADC while providing signal gain. The OPAx354-Q1 family of devices is designed for applications requiring high DC accuracy.

Figure 6-5 shows the OPAx354-Q1 family of devices driving an ADC. With the OPAx354-Q1 family of devices in an inverting configuration, using a capacitor across the feedback resistor can filter high-frequency noise in the signal.
