Op-Amp - TL071, Single, Low-Noise, JFET-input, 8-Pin DIP
TL071 single op amp in an 8-pin DIP package. The TL07xx JFET-input operational amplifier family is designed to offer a wider selection than any previously developed operational amplifier family. 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 currents, and low offset-voltage temperature coefficient. The low harmonic distortion and low noise make the TL07xseries ideally suited for high-fidelity and audio pre-amplifier applications.
Op-Amp - NJM4558, Dual high-gain, 8-Pin DIP
Dual Operational Amplifier. The NJM4558 (JRC4558) integrated circuit is a dual high-gain operational amplifier internally compensated and constructed on a single silicon chip using an advanced epitaxial process. Combining the features of the NJM741 with the close parameter matching and tracking of a dual device on a monolithic chip results in unique performance characteristics. Excellent channel separation allows the use of the dual device in single NJM741 operational amplifier applications providing density. It is especially well suited for applications in differential-in, differential-out as well as in potentiometric amplifiers and where gain and phase matched channels are mandatory. Features:
- Operating Voltage (±4V~±18V)
- High Voltage Gain (100dB typ.)
- High Input Resistance (5MΩ typ.)
- Bipolar Technology
Op-Amp - TL072, Dual, Low-Noise, JFET Input, 8-Pin DIP
The TL072 is a high speed JFET input dual operational amplifier incorporating well matched, high voltage JFET and bipolar transistors in a monolithic integrated circuit. The device features high slew rates, low input bias and offset current, and low offset voltage temperature coefficient.
Audio Power Amplifier - LM386N-1, Low Voltage
LM386 Low Voltage Audio Power Amplifier The LM386 is a mono low voltage amplifier that can be used in a variety of applications. It can drive loads from 4 Ω to 32 Ω. The gain is internally set to 20 but it can be modified from 20 to 200 by placing a resistor and capacitor between pins 1 and 8. As this is an Op Amp it can be used in different configurations to fit in several applications. The internal gain setting resistor allows the LM386 to be used in a very low part count system. In addition a series resistor can be placed between pins 1 and 5 to modify the gain and frequency response for specific applications. These are found in many small audio amplifiers and even tiny pedal sized guitar amplifiers! There are tons of possibilities for this little Op Amp.
Op-Amp - NJM5532, Dual, Low-Noise, 8-Pin DIP
The NJM5532 is a high performance dual low noise operational amplifier. Compared to the standard dual operational amplifiers, such as the NJM1458, it shows better noise performance, improved output drive capability, and considerably higher small-signal and power bandwidths. it is compensated internally for voltage follower circuit. This makes the device especially suitable for application in high quality and professional audio equipment, instrumentation, control circuits, and telephone channel amplifiers Features:
