This document describes how to optimize the performance of a 16-bit, 105Msps ADC by carefully designing the intermediate frequency (IF) signal chain to maximize overall system performance. The article provides detailed information on the signal chain topology and design considerations for each stage. Finally, the LTC2274 ADC is recommended as an excellent choice with excellent AC performance and high dynamic range.

The LTC®3605 is a high efficiency, monolithic synchronous step-down switching regulator that is capable of delivering 5A of continuous output current from input voltages of 4V to 15V.

The LTC4217 is a high-performance 2A hot swap controller that integrates the MOSFET and sense resistor, for accurate current limiting and load current monitoring in tight spaces.

Introduces a ultralow power boost converter, which only needs 8.5µA of standby quiescent current, and is suitable for applications that need to be in standby mode for a long time, such as industrial remote monitoring systems and keep-alive circuits.

The LTC4099 USB power manager and Li-Ion/Polymer battery charger seamlessly manages power distribution from multiple sources in portable applications. It is differentiated from other USB power managers by its bidirectional I2C port that allows the host microprocessor to control and monitor all aspects of the USB power management and battery charging processes.

This document describes a high-efficiency USB power management system that safely charges Li-Ion/Polymer batteries from automotive power supplies. The system is compact, robust, efficient, and easy to design, making it suitable for use in large transient environments.
