description/ordering information
These JFET-input operational amplifiers incorporate well-matched high-voltage JFET and bipolar transistors
in a monolithic integrated circuit. They feature low input offset voltage, high slew rate, low input bias and offset
currents, and low temperature coefficient of input offset voltage. Offset-voltage adjustment is provided for the
TL087 and TL088.
The C-suffix devices are characterized for operation from 0°C to 70°C, and the I-suffix devices are characterized
for operation from −40°C to 85°C. The M-suffix devices are characterized for operation over the full military
temperature range of −55°C to 125°C.

All voltage values, except differential voltages, are with respect to the midpoint between VCC+ and VCC−.
Differential voltages are at the noninverting input terminal with respect to the inverting input terminal.
The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 V, whichever is less.
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.
Maximum power dissipation is a function of TJ(max), qJA, and TA. The maximum allowable power dissipation at any allowable ambient
temperature is PD = (TJ(max) – TA)/qJA. Operating at the absolute maximum TJ of 150°C can affect reliability.
The package thermal impedance is calculated in accordance with JESD 51-7.
The output may be shorted to ground or to either supply. Temperature and/or supply voltages must be limited to ensure that the

All characteristics are measured under open−loop conditions with zero common-mode input voltage, unless otherwise specified. Full range for TA is −55°C to 125°C for TL_88M;
−40°C to 85°C for TL_8_I; and 0°C to 70°C for TL_8_C.
‡ Input bias currents of an 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.

Typical values as presented in this data sheet represent the median (50% point) of device parametric
performance.
input bias and offset current
At the picoamp bias current level typical of these JFET operational amplifiers, accurate measurement of the bias
current becomes difficult. Not only does this measurement require a picoammeter, but test socket leakages can
easily exceed the actual device bias currents. To accurately measure these small currents, Texas Instruments
uses a two-step process. The socket leakage is measured using picoammeters with bias voltages applied, but
with no device in the socket. The device then is inserted in the socket and a second test that measures both
the socket leakage and the device input bias current is performed. The two measurements then are subtracted
algebraically to determine the bias current of the device.

TYPICAL APPLICATION DATA
output characteristics
All operating characteristics are specified with 100-pF load capacitance. These amplifiers will drive higher
capacitive loads; however, as the load capacitance increases, the resulting response pole occurs at lower
frequencies, causing ringing, peaking, or even oscillation. The value of the load capacitance at which oscillation
occurs varies with production lots. If an application appears to be sensitive to oscillation due to load capacitance,
adding a small resistance in series with the load should alleviate the problem. Capacitive loads of 1000 pF, and
larger, may be driven if enough resistance is added in series with the output (see Figure 43).

TYPICAL APPLICATION DATA
input characteristics
These amplifiers are specified with a minimum and a maximum input voltage that, if exceeded at either input,
could cause the device to malfunction.
Because of the extremely high input impedance and resulting low bias current requirements, these amplifiers
are well suited for low-level signal processing; however, leakage currents on printed circuit boards and sockets
easily can exceed bias current requirements and cause degradation in system performance. It is good practice
to include guard rings around inputs (see Figure 45). These guards should be driven from a low-impedance
source at the same voltage level as the common-mode input.

noise performance
The noise specifications in operational amplifier circuits are greatly dependent on the current in the first-stage
diflferential amplifier. The low input bias current requirements of these amplifiers result in a very low current
noise. This feature makes the devices especially favorable over bipolar devices when using values of circuit
impedance greater than 50 kΩ.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS
compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
