DESCRIP T ION

Thesecircuitsconsistoftwoindependent,highgain, internally frequency compensated which were designedspecificallytooperatefromasinglepower supplyoverawiderangeofvoltages.Thelowpower supplydrainis independentofthemagnitudeof the powersupply voltage.

Applicationareasincludetransduceramplifiers, dc gainblocksandalltheconventionalop-ampcircuits whichnowcanbemoreeasilyimplementedinsingle powersupply systems. For example,thesecircuits canbedirectlyoperatedoff thestandard+5Vpower supply voltage which is used in logic systems and willeasily providetherequiredinterfaceelectronics withoutrequiringany additionalpowersupply.

In the linearmodetheinput common-modevoltage range includes ground and the output voltage can also swing to ground, even though operated from onlya singlepower supplyvoltage.

The gain-bandwidth product is temperature compensated.

tor-base junction 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 cause the output voltages of the Op-amps to go to the V duration that an input is driven negative. This is not destructive and normal output will set up again for input voltage higher than –0.3V.
