AD9645BCPZ-80

Analog To Digital Converters (ADC) Overview

The AD9645BCPZ-80 is a dual-channel, 14-bit analog-to-digital converter (ADC) from Analog Devices Inc., operating at a maximum sampling rate of 80 MSPS. It features a multistage pipelined architecture with on-chip sample-and-hold circuits and integrated output error correction logic. The device requires a single 1.8 V supply for both analog and digital domains. Digital outputs are provided via serial LVDS interfaces compliant with ANSI-644 standards. Key performance metrics include a signal-to-noise ratio (SNR) of 75.6 dBFS at 9.7 MHz input frequency and a spurious-free dynamic range (SFDR) of 96 dBc at the same frequency. The component is housed in a 32-lead LFCSP package.
