DESCRIPTION
The ADS5410 is a high-speed, high-performance pipelined analog-to-digital converter with exceptionally low-noise
and high spurious-free dynamic range. The ADS5410 high input bandwidth makes it ideal for IF subsampling
solutionswheredigitalI/Q demodulatorsareused. Itshighdynamicrangemakesit wellsuitedforGSM, IS-95, UMTS,
and IS-136 digital receivers. Its linearity and low DNL make it ideal for medical imaging applications. Low power
consumption makes the ADS5410 ideal for applications in compact pico- and micro-base stations and in portable
designs.
