AD9445BSVZ-125

Analog To Digital Converters (ADC) Overview

The AD9445BSVZ-125 is a 14-bit, monolithic sampling analog-to-digital converter (ADC) with an on-chip IF sampling track-and-hold circuit. It operates at a guaranteed maximum conversion rate of 125 MSPS and requires 3.3 V and 5.0 V power supplies. The device features buffered differential analog inputs with selectable full-scale ranges of 2.0 V p-p or 3.2 V p-p. Digital outputs are available in either CMOS or LVDS formats, compliant with ANSI-644 standards. It includes an internal reference, clock duty cycle stabilizer, and out-of-range detection capabilities.
