MIC7122
Rail-to-Rail Dual Op Amp
Preliminary Information
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 100k⦠load.
The amplifiers operate from 2.2V to 15V and are fully speci-
fied 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 pack-
age.
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, 2kâ¦)
⢠Drives 200pF at 5V and greater supply voltages
Applications
⢠Battery-powered instrumentation
⢠PCMCIA, USB peripherals
⢠Portable computers and PDAs
