Product Introduction

Overview

The LTC2298CUP, produced by Analog Devices Inc., is a high-performance, dual 14-bit analog-to-digital converter (ADC) designed for digitizing high-frequency, wide dynamic range signals. This ADC operates at a sampling rate of up to 65 Msps and is optimized for low power consumption, making it suitable for demanding applications in imaging and communications.

With its single 3V supply and separate output supply, the LTC2298CUP can drive logic levels from 0.5V to 3.6V. It features a pipeline architecture, a clock duty cycle stabilizer, and shutdown and nap modes for power management. The device is available in a 64-lead QFN package and is RoHS compliant.
