It operatesfrom a single power supplyover a wide range of voltages. The low powersupply drain is independentof the magnitude of thepower supply voltage.Application areas include transducer amplifiers, dcgain blocks and all the conventionalop-amp circuitswhich nowcan bemore easily implementedin singlepower supply systems. For example, these circuitscan be directly supplied with off the standard + 5Vwhich is usedin logic systems and will easily providethe required interface electronics without requiringany additional power supply.In the linear mode the input common-mode voltagerange includes ground and the output voltage canalso swing to ground, even though operated fromonly a single power supply voltage.January 1999Part Temperature PackageNumber Range N D PLM2904 -40 o C, +125 o C • • •Example : LM2904DPIN CONNECTIONS (top view)123-+ -4 + 51 - Output 15 - Non-inverting input 22 - Inverting input 16 - Inverting input 23 - Non-inverting input 1 7 - Ouput 24-VCC - 8-VCC +8761/12

This input current only exist when the voltage at any of the input leads is driven negative. It is due to the collector-basejunction of the input PNP transistor becoming forward biased and thereby acting as input diode clamps.In addition to this diode action, there is also NPN parasitic action on the IC chip. This transistor action can causethe output voltages of the Op-amps to go to the V CC voltage level (or to ground for a large overdrive) for the timeduration that an input is driven negative.This is not destructive and normal output will set up again for input voltage higher than –0.3V.2. Short-circuits from the output to V CC can cause excessive heating if V + CC > 15V. The maximum output current isapproximatively 40mA independent of the magnitude of V CC. Destructive dissipation can result from simultaneousshort-circuits on all amplifiers.3. V O = 1.4V, R S =0Ω,5V
