LTC2248IUH

LTC2248IUH Description

The LTC2248IUH from Analog Devices Inc. is a high-performance 14-bit pipelined analog-to-digital converter (ADC) designed for precision signal acquisition in demanding applications. Operating at a 65MSPS sampling rate, it supports both differential and single-ended input configurations, offering flexibility in system design. The device features a 1:1 sample-and-hold (S/H) to ADC ratio, ensuring accurate signal capture with minimal distortion. With parallel data interface and external/internal reference options, the LTC2248IUH simplifies integration into high-speed data acquisition systems. Housed in a compact 32-pin QFN package, it is optimized for surface-mount assembly and operates from 2.7V to 3.4V analog/digital supplies, making it suitable for low-power designs.
