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
V of both rails when driving a 100k
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/
s, respectively.
The MIC7300 is available in Micrel's IttyBittyTM SOT-23-5
package for space-conscious circuits and in high-power
MM8TM 8-lead MSOP for improved heat dissipation in higher
power applications.
