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.
The AD8012 is well suited for any application that requires high
performance with minimal power.
The product is available in standard 8-lead SOIC or MSOP
packages and operates over the industrial temperature range
–40°C to +85°C.
*Protected under U.S. Patent Number 5,537,079.
