I – Objectivos
Estudo de várias montagens com amplificadores operacionais: inversor, seguidor de tensão,
amplificador diferencial e comparador regenerativo (Schmitt trigger).
II – Material necessário

1 Resistência 1 kΩ
1 Resistência 1,5 kΩ
2 Resistências 47 kΩ
2 Resistências 100 kΩ
1 Resistência 1 MΩ
1 Potenciómetro 100 kΩ
Fonte de alimentação simétrica de +15V /0 /-15V e de +5V /0
Gerador de sinais
Osciloscópio
Chave de fendas de ajuste
Notas: Não se esqueça que o amplificador operacional tem que funcionar sempre alimentado.
Quando iniciar uma montagem, em primeiro lugar deverá estabelecer as ligações de
alimentação do ampop. Deverá mantê-las durante todo o trabalho, uma vez que são
comuns a todas as montagens. Todas as alterações que efectuar nos circuitos deverão ser
executadas com as fontes de sinal e de alimentação desligadas. O gerador de sinal só
deverá permanecer ligado enquanto o ampop estiver alimentado. Assim, a sequência de
operações deverá ser a seguinte:
1.
2.
3.
4.
5.
6.
7.
Com tudo desligado, efectuar as ligações necessárias.
Verificar se as ligações estão correctas, com o auxílio do docente.
Ligar a fonte de alimentação.
Ligar o gerador de sinal.
Efectuar os procedimentos e medições necessários ao trabalho.
Desligar o gerador de sinal.
Desligar a fonte de alimentação.
III – Condução do trabalho
1. Compensação do “offset”
1.1. Monte o circuito necessário (de acordo com o catálogo do fabricante) para proceder à
compensação do “offset” do ampop (TL071), com as entradas inversora e não-inversora
curto-circuitadas e ligadas à massa (0V). Não se esqueça de, em primeiro lugar, alimentar
o ampop com +15V/-15V.
1.2. Ajuste o potenciómetro por forma a obter uma tensão de saída com valor médio de 0V.
1.3. Mantenha as entradas curto-circuitadas mas ligue-as agora a uma tensão de 5VDC.
Determine o ganho de modo comum do ampop.

2. Montagem inversora
2.1. Estabeleça as ligações necessárias para obter uma montagem inversora com uma
resistência de entrada de 15KΩ e um ganho teórico de 10.
2.2. Aplique na entrada do circuito uma onda sinusoidal de 50mV de amplitude com uma
frequência de 1kHz.
2.3. Com o osciloscópio, observe simultaneamente as formas de onda da tensão de entrada e de
saída do circuito. Desenhe as formas de onda visualizadas.
2.4. Visualize a tensão diferencial de entrada do ampop. Compare-a com o valor teórico
esperado.
2.5. Calcule o valor do ganho de tensão real do circuito e compare-o com o ganho ideal
(teórico).
2.6. Substitua a resistência de realimentação, Rf, por uma resistência de 1MΩ e repita os pontos
2.2 a 2.5.
2.7. Retire a resistência Rf. Verifique e explique o que sucede à saída do circuito.
3. Seguidor de tensão
3.1. Efectue as ligações necessárias para obter um seguidor de tensão.
3.2. Aplique na entrada do circuito uma tensão sinusoidal com amplitude de 100mV e uma
frequência de 1kHz.
3.3. Com o osciloscópio, observe as tensões de entrada e de saída do circuito. Desenhe as
formas de onda visualizadas. Calcule o valor do ganho de tensão real do circuito e
compare-o com o ganho ideal (teórico).

esperado.

description
The JFET-input operational amplifiers in the TL07_ series are designed as low-noise versions of the TL08_
series amplifiers with low input bias and offset currents and fast slew rate. The low harmonic distortion and low
noise make the TL07_ series ideally suited for high-fidelity and audio preamplifier applications. Each amplifier
features JFET inputs (for high input impedance) coupled with bipolar output stages integrated on a single
monolithic chip.
The C-suffix devices are characterized for operation from 0°C to 70°C. 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.

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltage values, except differential voltages, are with respect to the midpoint between VCC+ and VCC – .
2. Differential voltages are at IN+ with respect to IN –.
3. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 V, whichever is less.
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.

† All characteristics are measured under open-loop conditions with zero common-mode voltage unless otherwise specified.
‡ Full range is TA = 0°C to 70°C for TL07_C,TL07_AC, TL07_BC and is TA = – 40°C to 85°C for TL07_I.
§ Input bias currents of a FET-input operational amplifier are normal junction reverse currents, which are temperature sensitive as shown in Figure 4. Pulse techniques must be used
that maintain the junction temperature as close to the ambient temperature as possible.

† Input bias currents of a FET-input operational amplifier are normal junction reverse currents, which are temperature sensitive as shown in
Figure 4. Pulse techniques must be used that will maintain the junction temperature as close to the ambient temperature as possible.
‡ All characteristics are measured under open-loop conditions with zero common-mode voltage unless otherwise specified. Full range is
TA = – 55°C to 125°C.
