Overview
The LTC2170CUKG-12, produced by Analog Devices Inc., is a high-performance 12-bit analog-to-digital converter (ADC) designed for simultaneous sampling of high-frequency, wide dynamic range signals. This 4-channel ADC is ideal for demanding communications applications where precision and accuracy are crucial. It boasts exceptional AC performance with a signal-to-noise ratio (SNR) of 71dB and a spurious free dynamic range (SFDR) of 90dB. The ultralow jitter of 0.15ps RMS enables seamless undersampling of IF frequencies, ensuring excellent noise performance across the board.
