General Description

The MIC7300 is a high-performance CMOS operational amplifier featuring rail-to-rail input and output with strong output drive capability. It is able to source and sink in excess of 80mA into large capacitive loads.

The input common-mode range extends beyond the rails by 300mV, and the output voltage typically swings to within 150µV of both rails when driving a 100kΩ load.

The amplifier operates from 2.2V to 10V and is fully specified at 2.2V, 3V, 5V, and 10V. Gain bandwidth and slew rate are 500kHz and 0.5V/µs, respectively.

The MIC7300 is available in Micrel’s IttyBitty™ SOT-23-5 package for space-conscious circuits and in high-power MM8™ 8-lead MSOP for improved heat dissipation in higher power applications.
