AD9637BCPZRL7-40

Analog To Digital Converters (ADC) Overview

The AD9637BCPZRL7-40 is an octal, 12-bit analog-to-digital converter (ADC) operating at up to 40 MSPS. It integrates eight independent ADC channels within a single 64-lead LFCSP package. The device utilizes a serial LVDS interface and operates on a single 1.8 V supply. Key electrical specifications include a typical signal-to-noise ratio of 71.5 dBFS, a spurious-free dynamic range of 92 dBc, and a full-power analog bandwidth of 650 MHz. Power consumption is rated at 60 mW per channel at maximum speed.
