AD9257 Overview
Key Specifications
Package: LFCSP EP
Pins: 64
Operating Voltage: 1.8 V
Max Voltage (typical range): 1.9 V
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.
