PRODUCT DESCRIPTION  
The AD8012 is a dual, low power, current feedback amplifier  
capable of providing 350 MHz bandwidth while using only  
1.7 mA per amplifier. It is intended for use in high frequency,  
wide dynamic range systems where low distortion and high  
speed are essential and low power is critical.

With only 1.7 mA of supply current, the AD8012 also offers  
exceptional ac specifications such as 20 ns settling time and  
2,250 V/µs slew rate. The video specifications are 0.02% differ-  
ential gain and 0.06 degree differential phase, excellent for such  
a low power amplifier. In addition, the AD8012 has a low offset  
of 1.5 mV.
