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.

Frequency = 500 kHz

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.
