MIC7300

High-Output Drive Rail-to-Rail Op Amp

Preliminary Information

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

150

µV 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.
