Overview
The AD9002TD/883B 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). It features 256 parallel comparator stages and ECL-compatible output latches, making it suitable for high-speed applications. The AD9002TD/883B is known for its low input capacitance, low power consumption, and wide analog input bandwidth of 160 MHz, which allows accurate acquisition of high-speed pulse inputs without an external track-and-hold circuit.
