Overview
The AD9627ABCPZ-105, produced by Analog Devices Inc., is a dual, 12-bit analog-to-digital converter (ADC) designed to support communications applications where low cost, small size, and versatility are essential. This ADC features a multistage, differential pipelined architecture with integrated output error correction logic. Each ADC includes wide bandwidth differential sample-and-hold analog input amplifiers that support various user-selectable input ranges. An integrated voltage reference simplifies design considerations, and a duty cycle stabilizer ensures excellent performance by compensating for variations in the ADC clock duty cycle.
