Description
The TL061 is a high-speed JFET input single
operational amplifier, that incorporates well-
matched, high-voltage JFET and bipolar
transistors in a monolithic integrated circuit.
The device features high slew rates, low input
bias and offset currents, and 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 V
CC+
and V
CC-
.
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 cap 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.
