APPLICATIONS
Battery Powered Instruments
Hand-Held Scopemeters
Low Cost Digital Oscilloscopes GENERAL DESCRIPTION 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 3.0 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. FUNCTIONAL BLOCK DIAGRAM …
