产品型号TL081CP的概述

TL081CP芯片的概述 TL081CP是一种高性能的运算放大器,属于TL系列家族,广泛应用于模拟信号处理、音频设备、传感器应用和各种信号放大电路中。该芯片的设计目的是在低噪声和高增益情况下提供稳定的增益,同时能够支持宽频带宽。这使得TL081CP在音频处理、信号调理和精密测量等领域具有广泛的应用。 TL081CP内部集成了多种电路,包括输入差分放大器、增益阶段及输出缓冲器,支持单电源供电。它的出现大大简化了电路设计,提高了系统性能,并有效降低了组件数量,从而减少了物理空间的占用。 TL081CP的详细参数 TL081CP的主要电气参数如下: - 工作电压范围:±3V至±15V,或单电源+6V至+30V - 输入失调电压:最大200mV - 输入偏置电流:最大100pA - 增益带宽积:3 MHz - 增益:可调,开放增益可达100V/V - 输出电压摆幅:接近电源电压,通常达到Vcc...

TL081 Wide Bandwidth JFET  
Input Operational Amplifier  
are critical, the LF356 is recommended. If maximum supply  
current is important, however, the TL081C is the better  
choice.  
General Description  
The TL081 is a low cost high speed JFET input operational  
amplifier with an internally trimmed input offset voltage  
(BI-FET IITM technology). The device requires a low supply  
current and yet maintains a large gain bandwidth product  
and a fast slew rate. In addition, well matched high voltage  
JFET input devices provide very low input bias and offset  
currents. The TL081 is pin compatible with the standard  
LM741 and uses the same offset voltage adjustment circuit-  
ry. This feature allows designers to immediately upgrade the  
overall performance of existing LM741 designs.

Application Hints  
The TL081 is an op amp with an internally trimmed input  
offset voltage and JFET input devices (BI-FET II). 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 de-  
stroyed 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  
5
Application Hints (Continued)  
common-mode range again puts the input stage and thus  
the amplifier in a normal operating mode.  
resulting forward diode within the IC could cause fusing of  
the internal conductors and result in a destroyed unit.  
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.  
Because these amplifiers are JFET rather than MOSFET  
input op amps they do not require special handling.  
As with most amplifiers, care should be taken with lead  
dress, component placement and supply decoupling in or-  
der to ensure stability. For example, resistors from the out-  
put to an input should be placed with the body close to the  
input to minimize ‘‘pick-up’’ and maximize the frequency of  
the feedback pole by minimizing the capacitance from the  
input to ground.  
The amplifier will operate with a common-mode input volt-  
age equal to the positive supply; however, the gain band-  
width and slew rate may be decreased in this condition.  
When the negative common-mode voltage swings to within  
3V of the negative supply, an increase in input offset voltage  
may occur.  
A feedback pole is created when the feedback around any  
amplifier is resistive. The parallel resistance and capaci-  
tance from the input of the device (usually the inverting in-  
put) to AC ground set the frequency of the pole. In many  
instances the frequency of this pole is much greater than  
the expected 3 dB frequency of the closed loop gain and  
consequently there is negligible effect on stability margin.  
However, if the feedback pole is less than approximately 6  
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.  
The TL081 is biased by a zener reference which allows nor-  
g
mal circuit operation on 4V power supplies. Supply volt-  
ages less than these may result in lower gain bandwidth and  
slew rate.  
g
The TL081 will drive a 2 kX load resistance to 10V over  
a
the full temperature range of 0 C to 70 C. If the amplifier  
§
§
is forced to drive heavier load currents, however, an in-  
crease in input offset voltage may occur on the negative  
voltage swing and finally reach an active current limit on  
both positive and negative swings.  
Precautions should be taken to ensure that the power sup-  
ply for the integrated circuit never becomes reversed in po-  
larity or that the unit is not inadvertently installed backwards  
in  
a socket as an unlimited current surge through the
