PRODUCT DESCRIPTION
The AD9049 is a complete 9-bit monolithic sampling analog-
to-digital converter (ADC) with an onboard track-and-hold and
reference. The unit is designed for low cost, high performance
applications and requires only +5 V and an encode clock to
achieve 30 MSPS sample rates with 9-bit resolution.
The encode clock is TTL compatible and the digital outputs
are CMOS; both can operate with 5 V/3 V logic, selected by the
user. The two-step architecture used in the AD9049 is opti-
mized to provide the best dynamic performance available while
maintaining low power consumption.
A 2.5 V reference is included onboard, or the user can provide
an external reference voltage for gain control or matching of
multiple devices. Fabricated on an advanced BiCMOS process,
the AD9049 is packaged in space saving surface mount pack-
ages (SOIC, SSOP) and is specified over the industrial
(–40
°
C to +85
°
C) temperature range.
