The HA17741 OPAMP is an internal phase compensation high-performance operational amplifier, that is appropriate for use in a wide range of applications in the test and control fields.The is an internal phase compensation high-performance operational amplifier, that is appropriate for use in a wide range of applications in the test and control fields.A multivibrator is a square wave generator that uses an RC circuit charge/discharge operation to generatethe waveform. Multivibrators are widely used as the square wave source in such applications as powersupplies and electronic switches.Multivibrators are classified into three types, astable multivibrators, which have no stable states,monostable multivibrators, which have one stable state, and bistable multivibrators, which have two stablestates.Figure 10 shows the circuit diagram for a quadrature sine wave oscillator. This circuit consists of twointegrators and a limiter circuit, and provides not only a sine wave output, but also a cosine output, that is,it also supplies the waveform delayed by 90°. The output amplitude is essentially determined by the limiter
circuit.The op amp may be marked with a dot in one corner of the top, or a notch in one end, or both. Pin 1 is at the cornerwith the dot. Pin 1 is the pin in the corner to the left of the notch, looking down. Pin numbering runs counterclockwisefrom pin 1. Looking down on the op amp, with pin 1 in the upper left corner, pin 4 is in the lower leftcorner, pin 5 in the lower right corner, and pin 8 in the upper right corner. See the pinout in Figure 1. Note that theop amp symbol is NOT printed on the package.
