MIC910 135MHz, Low-Power SOT-23-5 Op Amp General Description Features The MIC910 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, and features the tiny SOT-23-5 package.       Supply voltage range is from ±2.5V to ±9V, allowing the MIC910 to be used in low-voltage circuits or applications requiring large dynamic range. The MIC910 is stable driving any capacitive 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 MIC910 ideal for portable equipment.

MIC910 Application Information Power Supply Bypassing Regular supply bypassing techniques are recommended. A 10µF capacitor in parallel with a 0.1µF capacitor on both the positive and negative supplies is ideal. For best performance, all bypassing capacitors should be located as close to the op amp as possible and all capacitors should be low equivalent series inductance (ESL) and equivalent series resistance (ESR). Surface-mount ceramic capacitors are ideal. The MIC910 is a high-speed, voltage-feedback operational amplifier featuring very low supply current and excellent stability. This device is unity gain stable and capable of driving high capacitance loads. Driving High Capacitance The MIC910 is stable when driving any capacitance (see the “Gain Bandwidth and Phase Margin vs. Load Capacitance” graph in the Typical Characteristics section) making it ideal for driving long coaxial cables or other high-capacitance loads. Thermal Considerations The SOT-23-5 package, like all small packages, has a high thermal resistance. It is important to ensure the IC does not exceed the maximum operating junction (die) temperature of 85°C. The part can be operated up to the absolute maximum temperature rating of 125°C, but between 85°C and 125°C performance will degrade, in particular CMRR will reduce. Phase margin remains constant as load capacitance is increased. Most high-speed op amps are only able to drive limited capacitance. Note: increasing load capacitance does reduce the speed of the device (see the “Gain Bandwidth and Phase Margin vs. Load” in the Typical Characteristics section). In applications where the load capacitance reduces the speed of the op amp to an unacceptable level, the effect of the load capacitance can be reduced by adding a small resistor (
