Overview
The AD9002AJ is a high-speed, 8-bit monolithic analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is fabricated in an advanced bipolar process, enabling it to operate at sampling rates exceeding 150 million samples per second (MSPS). The AD9002AJ features a wide analog input bandwidth of 160 MHz, which allows for accurate acquisition of high-speed pulse inputs without the need for an external track-and-hold circuit. It is designed for applications requiring high-speed and high-accuracy data conversion.
