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. 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 temperature range (–40°C to +85°C).
