Beschreibung

This TI Verified Design provides the theory, component selection, TINA-TI simulations, Verification & Measurement Performance, Altium Schematics, PCB Layout for a Phase Compensated 8-Ch Multiplexed Data Acquisition System for Power Automation. The design uses a 16-bit, 8-Channel, 500ksps SAR ADC, ADS8688 with integrated analog front-end circuit for ease of system hardware design.The design introduces the concept of phase and phase Compensation, compares the additional phase delay introduced between the input channels of a non-simultaneous sampling ADC with a simultaneous sampling ADC, and provides a optimal algorithm to compensate for the phase delay introduced in a non-simultaneous implementation.Measured results demonstrate how the phase compensation algorithm used in this design compensates for the additional phase delay introduced by a multiplexed ADC, resulting in an equivalent performing solution as compared to a simultaneous sampling ADC solution.
