ADI AD9288BSTZ-40

The AD9288 is a dual 8-bit monolithic sampling analog-to-digital converter with on-chip track-and-hold circuits. It 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. Each channel can be operated independently. The ADC requires only a single 3.0 V (2.7 V to 3.6 V) 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 3.3 V or 2.5 V logic. The Encode input is TTL/CMOS-compatible, and the 8-bit digital outputs can be operated from 3.0 V (2.5 V to 3.6 V) supplies. User-selectable options offer a combination of standby modes, digital data formats, and digital data timing schemes. In standby mode, the digital outputs are driven to a high impedance state. Fabricated on an advanced CMOS process, the AD9288 is available in a 48-lead surface-mount plastic package 7 mm×7 mm, 1.4 mm LQFP) specified over the industrial temperature range (-40°C to +85°C). The AD9288 is pin-compatible with the 10-bit AD9218, facilitating future system migrations.
