200MHz Low-Power SOT-23-5 Op Amp Final Information
General Description
The MIC912 is a high-speed, operational amplifier with a gain-bandwidth product of 200MHz. The part is unity-gain stable provided its output is loaded with at least 200. It has a very low, 2.4mA supply current, and features the tiny SOT23-5 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.

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