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.
