The AD9648BCPZ-105 from Analog Devices is a 14-bit, 105 MSPS dual-channel analog-to-digital converter (ADC) operating from a single 1.8V supply. It features a high-performance sample-and-hold circuit with 650MHz analog input bandwidth, an on-chip voltage reference, and supports both CMOS and LVDS output logic. The device achieves 74.5 dBFS SNR and 91 dBc SFDR at 70MHz input, making it ideal for communications and imaging applications. The -105 suffix indicates the 105 MSPS speed grade, packaged in a 64-lead LFCSP.
