Description

The AD9434BCPZ-500 is a 12-bit Analog to Digital Converter (ADC) designed for high performance, ease of use and low power consumption. With a conversion rate of up to 500 MSPS, this chip is optimized for superior dynamic performance in broadband and wideband carrier systems. All required functions for signal conversion are included on the chip, including a voltage reference and sample-and-hold mechanism. Additionally, the chip can be operated with an external voltage reference if required.
