MIC7122
Rail-to-Rail Dual Op Amp
Micrel
General Description
The MIC7122 is a dual high-performance CMOS operational
amplifier featuring rail-to-rail inputs and outputs.
The input common-mode range extends beyond the rails by
300mV, and the output voltage swings to within 150µV of
both rails when driving a 100kΩ load.
The amplifiers operate from 2.2V to 15V and are fully
specified at 2.2V, 5V, and 15V. Gain bandwidth and slew
rate are 750kHz and 0.7V/µs, respectively at 2.2V supply.
The MIC7122 is available in the MM8™ 8-lead MSOP
package.
Features
• Small footprint MSOP-8 package
• 350µA supply current per op amp at 2.2V supply
• Guaranteed 2.2V, 5V, and 15V performance
• 750kHz gain-bandwidth product at 2.2V supply
• 0.01% total harmonic distortion at 1kHz (15V, 2kΩ)
• Drives 200pF at 5V and greater supply voltages
Applications
• Battery-powered instrumentation
• PCMCIA, USB peripherals
• Portable computers and PDAs
