FEATURES  
DESCRIPTION  
These are the first monolithic JFET input operational  
amplifiers to incorporate well matched, high voltage  
JFETs on the same chip with standard bipolar  
transistors ( BI-FET™ Technology). These amplifiers  
feature low input bias and offset currents/low offset  
voltage and offset voltage drift, coupled with offset  
adjust which does not degrade drift or common-mode  
rejection. The devices are also designed for high slew  
rate, wide bandwidth, extremely fast settling time, low  
voltage and current noise and a low 1/f noise corner.

and VOS, IB and IOS are measured at VCM = 0.  
(2) The Temperature Coefficient of the adjusted input offset voltage changes only a small amount (0.5μV/°C typically) for each mV of  
adjustment from its original unadjusted value. Common-mode rejection and open loop voltage gain are also unaffected by offset  
adjustment.  
(3) The input bias currents are junction leakage currents which approximately double for every 10°C increase in the junction temperature,  
TJ. Due to limited production test time, the input bias currents measured are correlated to junction temperature. In normal operation the  
junction temperature rises above the ambient temperature as a result of internal power dissipation, Pd. TJ = TA + θJA Pd where θJA is  
the thermal resistance from junction to ambient. Use of a heat sink is recommended if input bias current is to be kept to a minimum.  
(4) Supply Voltage Rejection is measured for both supply magnitudes increasing or decreasing simultaneously, in accordance with common  
practice.

(1) Settling time is defined here, for a unity gain inverter connection using 2 kΩ resistors for the LF155/6. It is the time required for the error  
voltage (the voltage at the inverting input pin on the amplifier) to settle to within 0.01% of its final value from the time a 10V step input is  
applied to the inverter. For the LF357, AV = 5, the feedback resistor from output to input is 2kΩ and the output step is 10V (See Settling  
Time Test Circuit).

APPLICATION HINTS  
These are op amps with JFET input devices. These JFETs have large reverse breakdown voltages from gate to  
source and drain eliminating the need for clamps across the inputs. Therefore large differential input voltages can  
easily be accommodated without a large increase in input current. The maximum differential input voltage is  
independent of the supply voltages. However, neither of the input voltages should be allowed to exceed the  
negative supply as this will cause large currents to flow which can result in a destroyed unit.  
Exceeding the negative common-mode limit on either input will force the output to a high state, potentially  
causing a reversal of phase to the output. Exceeding the negative common-mode limit on both inputs will force  
the amplifier output to a high state. In neither case does a latch occur since raising the input back within the  
common-mode range again puts the input stage and thus the amplifier in a normal operating mode.  
Exceeding the positive common-mode limit on a single input will not change the phase of the output however, if  
both inputs exceed the limit, the output of the amplifier will be forced to a high state.  
These amplifiers will operate with the common-mode input voltage equal to the positive supply. In fact, the  
common-mode voltage can exceed the positive supply by approximately 100 mV independent of supply voltage  
and over the full operating temperature range. The positive supply can therefore be used as a reference on an  
input as, for example, in a supply current monitor and/or limiter.  
Precautions should be taken to ensure that the power supply for the integrated circuit never becomes reversed in  
polarity or that the unit is not inadvertently installed backwards in a socket as an unlimited current surge through  
the resulting forward diode within the IC could cause fusing of the internal conductors and result in a destroyed  
unit.  
All of the bias currents in these amplifiers are set by FET current sources. The drain currents for the amplifiers  
are therefore essentially independent of supply voltage.  
As with most amplifiers, care should be taken with lead dress, component placement and supply decoupling in  
order to ensure stability. For example, resistors from the output to an input should be placed with the body close  
to the input to minimize “pickup” and maximize the frequency of the feedback pole by minimizing the capacitance  
from the input to ground.  
A feedback pole is created when the feedback around any amplifier is resistive. The parallel resistance and  
capacitance from the input of the device (usually the inverting input) to AC ground set the frequency of the pole.  
In many instances the frequency of this pole is much greater than the expected 3dB frequency of the closed loop  
gain and consequently there is negligible effect on stability margin. However, if the feedback pole is less than  
approximately six times the expected 3 dB frequency a lead capacitor should be placed from the output to the  
input of the op amp. The value of the added capacitor should be such that the RC time constant of this capacitor  
and the resistance it parallels is greater than or equal to the original feedback pole time constant.

LF156 develops full Sr output capability for VIN 1V  
Addition of SW2 improves accuracy by putting the voltage drop across SW1 inside the feedback loop  
Overall accuracy of system determined by the accuracy of both amplifiers, A1 and A2  
Figure 56. High Accuracy Sample and Hold  
By closing the loop through A2, the VOUT accuracy will be determined uniquely by A1.  
No VOS adjust required for A2.  
TA can be estimated by same considerations as previously but, because of the added  
propagation delay in the feedback loop (A2) the overshoot is not negligible.

IMPORTANT NOTICE  
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other  
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest  
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and  
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale  
supplied at the time of order acknowledgment.  
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms  
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary  
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily  
performed.  
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and  
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide  
adequate design and operating safeguards.  
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or  
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information  
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or  
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the  
third party, or a license from TI under the patents or other intellectual property of TI.  
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration  
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
