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

solutions where digital I/Q demodulators are used. Its high dynamic range makes it well suited for GSM, 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.
