General Description

The AD9257 is an octal, 14-bit, 40 MSPS and 65 MSPS analogto-digital converter (ADC) with an on-chip sample-and-hold circuit designed for low cost, low power, small size, and ease of use.

The product operates at a conversion rate of up to 65 MSPS and is optimized for outstanding dynamic performance and low power in applications where a small package size is critical.

The ADC requires a single 1.8 V power supply and LVPECL-/ CMOS-/LVDS-compatible sample rate clock for full performance operation.
