GENERAL DESCRIPTION

The AD9051 is a complete 10-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 60 MSPS sample rates with 10-bit resolution.

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.

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 tem-

perature range (–40

°C to +85°C).
