Op-Amp - 4558, Dual high-gain, 8-Pin DIP
Dual Operational Amplifier. The 4558 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 $0.75 Op-Amp - BA4560, Dual, General Purpose, 8-Pin DIP The BA4560, is a dual operational amplifiers which achieves approximately twice the high output current of the BA4558, as well as featuring a higher slew rate of 4V / µs, a gain band width of 10MHz, and an improved frequency characteristic. 8-pin DIP package.$0.95 Op-Amp - LF353, Dual, Wide-Bandwidth, JFET Input, 8-Pin DIP Dual wide-bandwidth LF353 opamps in an 8-pin DIP package. The LF353 offers a high input impedance and 3MHz bandwidth. This LF353 device is a low-cost, high-speed, JFET input operational amplifier with very low input offset voltage. It requires low supply current yet maintains a large gain-bandwidth product and a fast slew rate. In addition, the matched high-voltage JFET input provides very low input bias and offset currents. $0.34 Op-Amp - LM324, Quad, Low-Power, 14-Pin DIP Quad low-power opamps in an 14-pin DIP package. The LM324 offers a 1MHz bandwidth and can be powered from a single supply.$0.18 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. $1.25 Op-Amp - LM741, Single, general purpose, 8-Pin DIP LM741 single opamp in an 8-pin DIP package. The LM741 has been used in classic guitar pedals such as the Distortion Plus. The LM741 series are general purpose operational amplifiers which feature improved performance over industry standards like the LM709. They are direct, plug-in replacements for the 709C, LM201, MC1439 and 748 in most applications. The amplifiers offer many features which make their application nearly foolproof: overload protection on the input and output, no latch-up when the common mode range is exceeded, as well as freedom from oscillations.$0.79 Op-Amp - M5201, Dual, With Switch, 8-Pin DIP The NJM2120 is a dual operational amplifier of 2-INPUT and 1-OUTPUT with analog switch. The NJM2120 can be used as analog switch under the condition of GV=0dB, as Switch + Amp in order that each gain (A or B) can be adjusted independently. Each amplifier of the NJM2120 has the same electrical characteristics as the NJM4558. The NJM2120 is suitable for audio, video, electrical musical instrument, etc. $4.50 Op-Amp - NE5532, Dual, Low-Noise, 8-Pin DIP This 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.
