TM MP8103 Dual Ultra Low Power 1.8V, 600kHz Op Amp The Future of Analog IC Technology TM DESCRIPTION FEATURES The MP8103 is a single supply, dual rail-to-rail output operational amplifier. This amplifier provides 600KHz bandwidth while consuming an incredibly low 14µA of supply current. The MP8103 can operate with a single supply voltage as low as 1.8V. The input common mode can go below the negative rail. The maximum supply voltage is 5.5V which allows the device to operate from ±0.9V to ±2.75V or a single supply. The MP8103 is available in an 8pin 3mm x 5mm MSOP package. • • • • • • • • • Single Supply Operation: 1.8V to 5.5V 600KHz –3dB Bandwidth 14µA Supply Current Rail-to-Rail Output Unity-Gain Stable Input Common Mode to Ground Drives Up to 1000pF of Capacitive Loads High Slew Rate: 0.1V/µs Available in a MSOP8 Package APPLICATIONS • • • • • • • • Portable Equipment PDAs Pagers Cordless Phones Handheld GPS Consumer Electronics Smoke Detector Portable Medical Equipment “MPS” and “The Future of Analog IC Technology” are Registered Trademarks of Monolithic Power Systems, Inc.

APPLICATION INFORMATION Power Supply Bypassing Regular supply bypassing techniques are recommended. A 10µF capacitor in parallel with a 0.1µF capacitor on both the positive and negative supplies is ideal. For the best performance, all bypassing capacitors should be located as close to the op amp as possible and all capacitors should be low ESL (Equivalent Series Inductance) and low ESR (Equivalent Series Resistance). Surface mount ceramic capacitors are ideal. MP8103 Rev. 0.9 8/9/2006 www.MonolithicPower.com MPS Proprietary Information. Unauthorized Photocopy and Duplication Prohibited. © 2006 MPS.
