Overview
The AD9012AQ is an 8-bit, ultrahigh-speed analog-to-digital converter (ADC) manufactured by Analog Devices Inc. This device is fabricated in an advanced bipolar process, enabling it to operate at sampling rates of up to 100 megasamples per second. It features 256 parallel comparator stages whose outputs are decoded to drive TTL-compatible output latches. The AD9012AQ is known for its exceptionally wide large-signal 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.
