MIC915
Dual 135MHz Low-Power Op Amp
General Description
The MIC915 is a high-speed, unity-gain stable operational amplifier. It provides a gain-bandwidth product of 135MHz with a very low, 2.4mA supply current per op amp. Supply voltage range is from ±2.5V to ±9V, allowing the MIC915 to be used in low-voltage circuits or applications requiring large dynamic range. The MIC915 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 MIC915 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.
