Overview
The LTC2159IUK, manufactured by Analog Devices Inc., is a high-performance 16-bit analog-to-digital converter (ADC) designed to meet the demands of modern communications and other high-frequency signal processing applications. This converter stands out with its exceptional AC performance, including a signal-to-noise ratio (SNR) of 77dB and a spurious free dynamic range (SFDR) of 90dB. The LTC2159IUK is particularly suited for applications requiring precise digitization of high-frequency signals, thanks to its ultralow jitter of 0.07ps RMS and a full power bandwidth of 550MHz for the sample-and-hold (S/H) circuit.
