AD9283BRSZ-RL50

The AD9283 is an 8-bit monolithic sampling analog-to-digital converter with an on-chip track-and-hold circuit and is optimized for low cost, low power, small size and ease of use. The product operates at a 100 MSPS conversion rate, with outstanding dynamic performance over its full operating range. The ADC requires only a single 3.0V (2.7V to 3.6V) power supply and an encode clock for full performance operation. No external reference or driver components are required for many applications. The digital outputs are TTL/CMOS compatible and a separate output power supply pin supports interfacing with 3.3V or 2.5V logic. The encoder input is TTL/CMOS compatible. A power-down function may be exercised to bring total consumption to 4.2mW. In power-down mode, the digital outputs are driven to a high impedance state. Fabricated on an advanced CMOS process, the AD9283 is available in a 20-lead surface mount plastic package (SSOP) specified over the industrial temperature range (-40°C to +85°C)
