MIC918 Micrel MIC918 51MHz Low-Power SOT-23-5/SC-70 Op Amp Final Information General Description Features The MIC918 is a high-speed operational amplifier with a 51MHz gain bandwidth product gain-bandwidth product of 51MHz. The part is unity gain 550 A supply current stable. Ithas a very low 550A supply current, and features SOT-23-5 or SC-70 packages the IttyBitty SOT-23-5 package and SC-70 package. 1500V/ s slew rate Supply voltage range is from 2.5V to 9V, allowing the drives any capacitive load MIC918 to be used in low-voltage circuits or applications Unity gain stable requiring large dynamic range. The MIC918 is stable driving any capacitative load and Applications achieves excellent PSRR and CMRR, making it much Video easier to use than most conventional high-speed devices. Imaging Low supply voltage, low power consumption, and small Ultrasound packing make the MIC918 ideal for portable equipment. Portable equipment The ability to drive capacitative loads also makes it pos- Line drivers sible to drive long coaxial cables. Ordering Information Part Number Junction Temp.
