8.3.6 Driving Analog-to-Digital converters
The OPAx354 series op amps offer 60 ns of settling time to 0.01%, making the series a good choice for driving high- and medium-speed sampling A/D converters and reference circuits. The OPAx354 series provide an effective means of buffering the
A/D converter input capacitance and resulting charge injection while providing signal gain. For applications requiring high DC accuracy, the OPA350 series is recommended.
Figure 34 shows the OPAx354 driving an A/D converter. With the OPAx354 in an inverting configuration, a capacitor across the feedback resistor is used to filter high-frequency noise in the signal.
