AD9050数据手册ADI中文资料规格书

描述 Description

The AD9050 is a complete 10-bit monolithic sampling analog-to-digital converter (ADC) with an onboard track-and-hold andreference. The unit is designed for low cost, high performanceapplications and requires only +5 V and an encode clock toachieve 40 MSPS or 60 MSPS sample rates with 10-bit resolution.The encode clock is TTL compatible and the digital outputsare CMOS; both can operate with 5 V/3 V logic, selected by theuser. The two-step architecture used in the AD9050 is optimizedto provide the best dynamic performance available whilemaintaining low power consumption. A 2.5 V reference is included onboard, or the user can providean external reference voltage for gain control or matching ofmultiple devices. Fabricated on an advanced BiCMOS process,the AD9050 is packaged in space saving surface mountpackages (SOIC, SSOP) and is specified over the industrial(-40°C to +85°C) temperature range. The 60 MSPS version(AD9050BRS-60) is only available in the SSOP package.
