The AD9257 is an 8-channel, 14-bit, 40 MSPS/65 MSPS analog-to-digital converter (ADC) with built-in sample-and-hold circuitry. It is designed for low-cost, low-power, and small-size applications, offering a conversion rate up to 65 MSPS with excellent dynamic performance. The device operates from a single 1.8 V supply and supports LVDS, LVPECL, and CMOS-compatible clock signals without requiring external reference voltage sources or drivers for many applications.
