MIC7122

MIC7122 Micrel MIC7122 Rail-to-Rail Dual Op Amp Preliminary Information 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.
