Product Introduction

Overview

The LTC2267IUJ-12 is a 12-bit, dual-channel, simultaneous sampling analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is designed to digitize high-frequency, wide dynamic range signals, making it ideal for demanding communications applications. It features low power consumption, high signal-to-noise ratio (SNR), and spurious free dynamic range (SFDR), along with ultralow jitter, which allows for excellent noise performance even when undersampling IF frequencies.
