LTC2297IUP

LTC2297IUP Description

The LTC2297IUP from Analog Devices Inc. is a high-performance 14-bit, dual-channel pipelined analog-to-digital converter (ADC) designed for precision signal acquisition in demanding applications. Operating at a 40 MSPS (Mega Samples Per Second) sampling rate, it supports both differential and single-ended input configurations, offering flexibility in system design. The device features simultaneous sampling for both channels, ensuring accurate phase and timing alignment—critical for applications like communications, medical imaging, and instrumentation. With 2.7V to 3.4V analog and digital supply voltages, it is optimized for low-power, mixed-signal systems. Packaged in a 64-QFN tube format, it is suited for surface-mount PCB integration.

LTC2297IUP Features

• 14-bit resolution with 40 MSPS sampling rate for high-speed, high-accuracy conversion.
• Dual-channel architecture with simultaneous sampling, ideal for multi-channel systems.
• Supports differential and single-ended inputs for versatile signal conditioning.
• Pipelined ADC architecture ensures low latency and high throughput.
• External or internal reference options for system-level flexibility.
• Low-voltage operation (2.7V–3.4V) reduces power consumption in portable and embedded designs.
• 64-QFN package with MSL 1 (unlimited) moisture sensitivity, ensuring reliability in production environments.

LTC2297IUP Applications
