105MHz Low-Power SOT-23-5 Op Amp Final Information
General Description
The MIC911 is a high-speed operational amplifier which is unity gain stable regardless of resistive and capacitive load. It provides a gain-bandwidth product of 105MHz, a very low 1.25mA supply current, and features the IttybittyTM SOT-23-5 package. Supply voltage range is from ±2.5V to ±9V, allowing the MIC911 to be used in low-voltage circuits or applications requiring large dynamic range. The MIC911 is stable driving any capacitative load and achieves excellent PSRR and CMRR, making it much easier to use than most conventional high-speed devices. Low supply voltage, low power consumption, and small packing make the MIC911 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. Exceeding the maximum differential input voltage will damage the input stage and degrade performance (in particular, input bias current is likely to change). Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF. Output swing limited by the maximum output sink capability, refer to the short-circuit current vs. temperature graph in "Typical Characteristics."
