general description the HT358 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 HT358 a good choice for battery operation. the HT358 is a versatile, rugged workhorse with a thousand-and-one us e, 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~40v(or 1.5v~ 16v), ? input common-mode voltage range includes ground ? large output voltage swing:0v dc to vcc-1.5v dc. ? low input offset voltage:2mv(typ.),and offet current 5nadc ? wide bandwidth (unity gain): 1 mhz package outline: dip8, sop8 applications ? cordless telephone ? switching power supply ? battery chargers internal diagram logic diagram 1 of 6 4008-318-123 sales@twtysemi.com http://www.twtysemi.com product specification HT358
