AD9628BCPZ-125

Analog To Digital Converters (ADC) Overview

The AD9628BCPZ-125 is a monolithic, dual-channel, 12-bit analog-to-digital converter (ADC) operating at sampling rates up to 125 MSPS. It utilizes a multistage differential pipeline architecture with output error correction logic to guarantee no missing codes across the full industrial temperature range of −40°C to +85°C. The device operates from a single 1.8 V analog supply and features an on-chip voltage reference and high-performance sample-and-hold circuit. Key electrical specifications include a signal-to-noise ratio (SNR) of 71.2 dBFS and a spurious-free dynamic range (SFDR) of 93 dBc at a 70 MHz input frequency. Power consumption is rated at 101 mW per channel at maximum speed.
