MIC7300 Micrel MIC7300 High-Output Drive Rail-to-Rail Op Amp General Description Features The MIC7300 is a high-performance CMOS operational Small footprint SOT-23-5 and power MSOP-8 packages amplifier featuring rail-to-rail input and output with strong >80mA peak output sink and source with 5V supply output drive capability. It is able to source and sink in excess Drives large capacitive loads (6000pF with 10V supply) of 80mA into large capacitive loads. Guaranteed 2.2V, 3V, 5V, and 10V performance 500kHz gain-bandwidth product The input common-mode range extends beyond the rails by 0.01% total harmonic distortion at 1kHz (10V, 2k ) 300mV, and the output voltage typically swings to within 1mA typical power supply current at 5V 150 V of both rails when driving a 100k load. Applications 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 Battery-powered instrumentation 500kHz and 0.5V/ s, respectively. PCMCIA, USB peripherals The MIC7300 is available in Micrels IttyBitty SOT-23-5 Portable computers and PDAs package for space-conscious circuits and in high-power MM8 8-lead MSOP for improved heat dissipation in higher power applications.
