description the ams lm358 consists two independent high gain operational amplifiers with internal compensated . the two op-amps operate over a wide voltage range from a single power supply. also use a split power supply. the device has low power supply voltage. the low power drain also makes the ams lm358 a good choice for battery operation. when your project calls for a traditional op-amp function, now you can streamline your design with a simple any digital system or personal co mputer application, without requiring an extra 15v power supply just to have the interface electronics you need. the ams lm358 is a versatile, rugged workhorse with a th ousand-and-one use, from amplifying signals from a variety of transducers to drain blocks, or any op-amp function. the attached pages offer some recipes that will have your project cooking in no time. features ? internally frequency compensated for unity gain ? large dc voltage gain:100db wide power supply range: 3v~30v(or 1.5v~ 15v) ? input common-mode voltage range includes ground ? large output voltage swing:0v dc to vcc-1.5v dc ? power drain suitable for battery operation ? differential inpit voltage and offset current ? wide gain bandwidth product: 5 mhz slew rate: 2v/s ? package outline: dip8, soic8 applications ? cordless telephone ? switching power supply ? battery chargers internal diagram logic diagram AMS358 advanced monolithic systems http://www.ams-semitech.com 1
