Description

The TL062, TL062A and TL062B are high-speed JFET input single operational amplifiers. Each of these JFET input operational amplifiers incorporates well matched, high-voltage JFET and bipolar transistors in a monolithic integrated circuit.

The devices feature high slew rates, low input bias and offset currents, and a low offset voltage temperature coefficient.

1.All voltage values, except differential voltage, are with respect to the zero reference level (ground) of the supply voltages where the zero reference level is the midpoint between VCC+ and VCC-.

2.The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 volts, whichever is less.

3.Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.

4.The output may be shorted to ground or to either supply. Temperature and/or supply voltages must be limited to ensure that the dissipation rating is not exceeded.

5.Short-circuits can cause excessive heating and destructive dissipation.

6.Rth are typical values.

7.Human body model: 100 pF discharged through a 1.5 kΩ resistor between two pins of the device, done for all couples of pin combinations with other pins floating.

8. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5 Ω), done for all couples of pin combinations with other pins floating.

9.Charged device model: all pins plus package are charged together to the specified voltage and then discharged directly to the ground.

1.The input bias currents of a FET-input operational amplifier are normal junction reverse currents, which are temperature sensitive. Pulse techniques must be used that will maintain the junction temperature as close to the ambient temperature as possible.
