TL071
Low noise JFET single operational amplifier
Features
■Wide common-mode (up to VCC+) and
differential voltage range
■Low input bias and of fset currenT
■Low noise en = 15 nV/ √Hz (typ)
■Output short-circuit pro tection
■High input impedance JFET input stage
■Low harmonic distortion: 0.01% (typ)
■Internal frequency compensation
■Latch-up free operation
■High slew rate: 16 V /µs (typ)
Description
The TL071, TL071A and TL071B 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 curr ents, and low offset voltage
temperature coe ff icie nt.

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 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. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-circuits on all
amplifiers.
5. Rth are typical values.
6. 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.
7. Human body model: 100pF discharged through a 1.5kΩ resistor between two pins of the device, done for all couples of pin
combinations with other pins floating.
8. Machine model: a 200pF cap is charged to the specified voltage, then discharged directly between two pins of the device
with no external series resistor (internal resistor < 5Ω), 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.
