Overview
The AD9002BJ is a high-speed, 8-bit monolithic analog-to-digital converter (ADC) manufactured by Analog Devices Inc. This device is designed for high-performance applications requiring rapid conversion rates and high accuracy. Fabricated in an advanced bipolar process, the AD9002BJ operates at sampling rates exceeding 150 million samples per second (MSPS). It features an innovative comparator design and careful device layout, resulting in a wide analog input bandwidth of 160 MHz. This allows for accurate acquisition of high-speed pulse inputs without the need for an external track-and-hold circuit. The AD9002BJ is suitable for a variety of demanding applications, including radar systems, digital oscilloscopes, and electronic warfare equipment.
