AD9641BCPZRL7-155

Analog To Digital Converters (ADC) Overview

The AD9641BCPZRL7-155 is a single-channel, 14-bit analog-to-digital converter (ADC) operating at a maximum sampling rate of 155 MSPS. It utilizes a multistage differential pipelined architecture with integrated output error correction logic and features a JESD204A high-speed serial interface. The device operates from a single 1.8 V supply, consuming 313 mW at full speed. Key electrical specifications include an SNR of 72.8 dBFS at 70 MHz input frequency, an SFDR of 90 dBc, and a programmable internal voltage reference. It supports flexible analog input ranges from 1.4 V p-p to 2.1 V p-p and includes an ADC clock duty cycle stabilizer.
