Test equipment GENERAL DESCRIPTION
The AD9257-EP is an octal, 14-bit, 65 MSPS analog-to-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 …
