Micrel, Inc.
230MHz Low-Power SC-70 Op Amp
General Description
The MIC922 is a high-speed operational amplifier with a
gain-bandwidth product of 230MHz. The part is unity gain
stable. It has a very low 2.5mA supply current, and features
the Teeny™ SC-70 package.
Supply voltage range is from ±2.5V to ±9V, allowing the
MIC922 to be used in low-voltage circuits or applications
requiring large dynamic range.
The MIC922 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 MIC922 ideal for portable equipment. The ability
to drive capacitative loads also makes it possible to drive
long coaxial cables.
Features
• 230MHz gain bandwidth product
• 400MHz –3dB bandwidth
• 2.5mA supply current
• SC-70 package
• 1500V/µs slew rate
• Drives any capacitive load
• Unity gain stable
Applications
• Video
• Imaging
• Ultrasound
• Portable equipment
• Line drivers
