Overview
The LTC2206IUK, produced by Analog Devices Inc., is a high-performance 16-bit analog-to-digital converter (ADC) designed for digitizing high-frequency, wide dynamic range signals. This ADC is part of the LTC2206 series, which includes variants with different sampling rates and bit resolutions. The LTC2206IUK is particularly suited for demanding communications applications due to its excellent AC performance, including a 78.2dB noise floor and 100dB spurious free dynamic range (SFDR). It features an ultralow jitter of 80fsRMS, enabling the undersampling of high input frequencies with superior noise performance.
