Improving Linearity by Using Absorptive Filters

Clarence Mayott - Applications Engineer Mar 10th 2017
Introduction: When driving a direct sampling high speed ADC, the most likely place to degrade the performance is the interface between the final amplifier and the ADC. With any direct sampling ADC there will be nonlinear charge produced in the sampling process. This charge is reflected into the input network each time the sampling ...

Get a 3dB SNR Boost Using a Dual ADC

Clarence Mayott - Applications Engineer Mar 4th 2013
Using a dual channel simultaneous sampling ADC and some simple averaging techniques, the SNR of the converter can be improved by 3dB. Step 1.  Collect data using both channels of the ADC using symmetrical input networks as shown below in Figure 1. This example uses the LTC2185 ADC and the LTC6409 amplifier.  There ...
