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.

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.
