Overview
The AD9257TCPZ-65-EP, produced by Analog Devices Inc., is an octal, 14-bit analog-to-digital converter (ADC) designed for low cost, low power, small size, and ease of use. This ADC operates at conversion rates of up to 65 MSPS and is optimized for outstanding dynamic performance and low power consumption. It features an on-chip sample-and-hold circuit and requires a single 1.8 V power supply. The device is suitable for applications where a small package size is critical and supports various clock and data alignment options, as well as built-in and custom digital test pattern generation.
