Overview
The LTC2230CUP, manufactured by Analog Devices Inc., is a high-performance 10-bit analog-to-digital converter (ADC) designed for digitizing high-frequency, wide dynamic range signals. This ADC operates at a sampling rate of 170 Msps and is particularly suited for demanding communications applications. It features excellent AC performance, including a signal-to-noise ratio (SNR) of 61 dB and a spurious free dynamic range (SFDR) of 75 dB for signals up to 200 MHz. The device is known for its ultralow jitter of 0.15 ps RMS, enabling the undersampling of IF frequencies with excellent noise performance.
