MIC912
200MHz Low-Power SOT-23-5 Op Amp
General Description
The MIC912 is a high-speed, unity-gain stable operational
amplifier. It provides a gain-bandwidth product of 200MHz
with a very low, 2.4mA supply current, and features the tiny
SOT-23-5 package.
Supply voltage range is from
2.5V to
9V, allowing the
MIC912 to be used in low-voltage circuits or applications
requiring large dynamic range.
The MIC912 is stable driving any capacitative load and
achieves excellent PSRR, making it much easier to use than
most conventional high-speed devices. Low supply voltage ,
low power consumption, and small packing make the MIC912
ideal for portable equipment. The ability to drive capacitative
loads also makes it possible to drive long coaxial cables.

Note 1.
Exceeding the absolute maximum rating may damage the device.
Note 2.
The device is not guaranteed to function outside its operating rating.
Note 3.
Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF.
Note 4.
Exceeding the maximum differential input voltage will damage the input stage and degrade performance (in particular, input bias current is
likely to increase).
