Overview
The AD9230BCPZ-170, produced by Analog Devices Inc., is a 12-bit monolithic sampling analog-to-digital converter (ADC) designed for high performance, low power consumption, and ease of use. This ADC operates at conversion rates up to 170 MSPS and is optimized for outstanding dynamic performance in wideband carrier and broadband systems. It includes all necessary functions such as a track-and-hold (T/H) and voltage reference on the chip, providing a complete signal conversion solution. The device requires a 1.8 V analog voltage supply and a differential clock for full performance operation. The digital outputs are LVDS (ANSI-644) compatible and support various data formats including twos complement, offset binary, and Gray code.
