T he AD9050 is a complete 10-bit monolithic sampling analog-  
to-digital converter (ADC) with an onboard track-and-hold and  
reference. T he unit is designed for low cost, high performance  
applications and requires only +5 V and an encode clock to  
achieve 40 MSPS or 60 MSPS sample rates with 10-bit resolution.

T he encode clock is T T L compatible and the digital outputs  
are CMOS; both can operate with 5 V/3 V logic, selected by the  
user. T he two-step architecture used in the AD9050 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 pro-  
cess, the AD9050 is packaged in space saving surface mount  
packages (SOIC, SSOP) and is specified over the industrial  
(–40°C to +85°C) temperature range. T he 60 MSPS version  
(AD9050BRS-60) is only available in the SSOP package.
