20-bit 1MSPS DAQ Reference Design Optimizing Power Supply Efficiency While Minimizing EMI
1 января 2018
This reference design for high performance data acquisition (DAQ) systems optimizes power stage in order to reduce power consumption and minimize the effect of EMI from switching regulator by using LMS3635-Q1 buck converter. This reference designs yields 7.2% efficiency improvement at most light load current compared to LM53635 buck converter, which achieves 125.25dB SFDR, 99dB SNR and 16.1ENOB.
Power design minimizing DC to DC EMI impact on system performance Two 20-bit SAR ADC channels Modular front-end reference design for high channel count systems that can be repeated Up to +/- 4V input signal (8Vpp differential)
