Overview
The AD9258BCPZRL7-125, produced by Analog Devices Inc., is a dual, 14-bit analog-to-digital converter (ADC) designed for high-performance applications. This ADC features a multistage, differential pipelined architecture with integrated output error correction logic. It is optimized for communications applications where high performance, low cost, small size, and versatility are crucial. The device operates from a single 1.8 V supply and a separate digital output driver supply, supporting 1.8 V CMOS or LVDS outputs. It is available in a 64-lead LFCSP package and is specified over the industrial temperature range of −40°C to +85°C.
