GENERAL DESCRIPTION
The AD9051 is a complete 10-bit monolithic sampling analogto-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 60 MSPS sample rates with 10-bit resolution.

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 a state-of-the-art BiCMOS
process, the AD9051 is packaged in a space saving surface
mount package (SSOP) and is specified over the industrial temperature range (–40°C to +85°C).
The encode clock is TTL compatible and the digital outputs are
CMOS; both can operate with 5 V/3 V logic. The two-step
architecture used in the AD9051 is optimized to provide the
best dynamic performance available while maintaining low
power consumption.
