Driving Lessons for a Low Nois

Designing an ADC driving topology that delivers uncompromising performance is challenging, especially when designing around an ultralow noise SAR ADC such as the
1Msps LTC2393-16. For both single-ended and differential
applications, a well thought out driving topology can fully
realize the ultralow noise and low distortion performance
required in your data acquisition system.
The LTC2393-16 is the first in a family of high performance
SAR ADCs from Linear Technology that utilizes a fully differential
architecture to achieve an excellent SNR of 94.2dB
and THD of –105dB. And in order to take full advantage
of the ADC performance, we present driving solutions
for both single-ended and differential applications. Both topologies fully demonstrate the ultralow noise and low distortion capabilities of the LTC2393-16.
