GENERAL DESCRIPTION
The AD9283 is an 8-bit monolithic sampling analog-to-digital
converter with an on-chip track-and-hold circuit and is opti-
mized for low cost, low power, small size and ease of use. The
product operates at a 100 MSPS conversion rate, with outstand-
ing 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.
The encoder input is TTL/CMOS compatible. A power-down
function may be exercised to bring total consumption to
4.2 mW. 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).
