Overview
The AD9283BRS-50 is an 8-bit monolithic sampling analog-to-digital converter (ADC) produced by Analog Devices Inc. This component is optimized for low cost, low power, small size, and ease of use, making it suitable for a variety of data acquisition applications. The AD9283BRS-50 operates at a sampling rate of 50 million samples per second (MSPS) and features an on-chip track-and-hold circuit. It requires only a single 3.0 V power supply (operating range of 2.7 V to 3.6 V) and an encode clock for full performance operation. The digital outputs are TTL/CMOS compatible, and the device supports a separate output power supply pin for interfacing with 3.3 V or 2.5 V logic.
