Overview
The AD9002AD is a high-speed, 8-bit monolithic analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is fabricated using an advanced bipolar process, enabling it to operate at sampling rates exceeding 150 million samples per second (MSPS). The AD9002AD features a wide analog input bandwidth of 160 MHz, making it suitable for accurate acquisition of high-speed pulse inputs without the need for an external track-and-hold circuit. It is designed to minimize false codes, ensuring high-speed linearity, and includes an overflow bit to indicate overrange inputs. The device is available in various temperature grades and packaging options, including industrial and military grades.
