portable equipment. Low distortion and fast settling make them  
ideal for active filter applications.  
The AD8051/AD8052/AD8054 offer low power supply cur-  
rent and can operate on a single +3 V power supply. These  
features are ideally suited for portable and battery powered  
applications where size and power are critical.  
APPLICATIONS  
Coax Cable Driver  
Active Filters  
Video Switchers  
A/D Driver  
The wide bandwidth and fast slew rate on a single +5 V supply  
make these amplifiers useful in many general purpose, high speed  
applications where dual power supplies of up to ±6 V and single  
supplies from +3 V to +12 V are needed.  
All of this low cost performance is offered in an 8-lead SOIC,  
along with a tiny SOT-23-5 package (AD8051), a µSOIC  
package (AD8052) and a TSSOP-14 (AD8054).

PRODUCT DESCRIPTION  
The AD8051 (single), AD8052 (dual) and AD8054 (quad) are  
low cost, voltage feedback, high speed amplifiers designed to  
operate on +3 V, +5 V or ±5 V supplies. They have true single  
supply capability with an input voltage range extending 200 mV  
below the negative rail and within 1 V of the positive rail.

Despite their low cost, the AD8051/AD8052/AD8054 provide  
excellent overall performance and versatility. The output volt-  
age swing extends to within 25 mV of each rail, providing the  
maximum output dynamic range with excellent overdrive recov-  
ery. This makes the AD8051/AD8052/AD8054 useful for video  
electronics such as cameras, video switchers or any high speed
