PRODUCT DESCRIPTION  
PRODUCT HIGHLIGHTS  
The AD9214 is a 10-bit monolithic sampling analog-to-digital  
converter (ADC) with an on-chip track-and-hold circuit, and  
is optimized for low cost, low power, small size, and ease of use.  
The product operates up to 105 MSPS conversion rate with  
outstanding dynamic performance over its full operating range.  
High Performance—Outstanding ac performance from 65 MSPS  
to 105 MSPS. SNR greater than 55 dB typical and as high  
as 58 dB.  
Low Power—The AD9214 at 285 mW consumes a fraction of  
the power available in existing high-speed monolithic solutions.  
In sleep mode, power is reduced to 30 mW.  
The ADC requires only a single 3.3 V (2.7 V to 3.6 V) power  
supply and an encode clock for full performance operation. No  
external reference or driver components are required for many  
applications. The digital outputs are TTL/CMOS compatible  
and a separate output power supply pin supports interfacing  
with 3.3 V or 2.5 V logic.  
Single Supply—The AD9214 uses a single 3 V supply, simplify-  
ing system power supply design. It also features a separate digital  
output driver supply line to accommodate 2.5 V logic families.  
Small Package—The AD9214 is packaged in a small 28-lead  
surface-mount plastic package (28-SSOP).  
The clock input is TTL/CMOS compatible. In the power-down  
state, the power is reduced to 30 mW. A gain option allows  
support for either 1 V p-p or 2 V p-p analog signal input swing.  
Fabricated on an advanced CMOS process, the AD9214 is  
available in a 28-lead surface-mount plastic package (28-SSOP)  
specified over the industrial temperature range (–40°C to +85°C).
