Efficient: LDO-Less: Power-Supply Network Reference Design for RF-Sampling ADC
Description
This reference design demonstrates a simplified and efficient network to power an ADC32RFxx. All three power domains of the analog-to-digital converter (ADC) are supplied using a switching regulator to enable the use of a power-supply network without a low-dropout (LDO) linear regulator. This configuration improves the overall power efficiency and reduces part count without any degradation to the ADC specifications.
Features
- Power efficiency increased by more than 10%Power savings of approximately 900 mWSmaller DC/DC solution size and fewer components than LDO-based designMaintains ADC performance metricsSupports single 5-V input
