Diode - 1N4739A, 9.1V, Zener, 1W, 5% Tolerance
1N4739A 9.1V zener diode in a DO-41 package. A semiconductor device that, above a certain reverse voltage(the zener value) has a sudden rise in current. If forward biased, the diode is an ordinary rectifier. When reverse biased, it exhibits a sharp break in its current-voltage graph. Voltage across the diode remains essentially constant for any further increase of reverse current.

Op-Amp - LM833, Dual, Low Distortion, Audio, 8-Pin DIP
LM833 dual op amp in an 8-pin dip package. The LM833 is a dual general purpose operational amplifier designed with particular emphasis on performance in audio systems. This dual amplifier IC utilizes new circuit and processing techniques to deliver low noise, high speed and wide bandwidth without increasing external components or decreasing stability. The LM833 is internally compensated for all closed loop gains and is therefore optimized for all preamp and high level stages in PCM and HiFi systems. The LM833 is pin-for-pin compatible with industry standard dual operational amplifiers. Features
  • Wide dynamic range: >140dB
  • Low input noise voltage: 4.5nV/ √ ^Hz
  • High slew rate: 7 V/μs (typ); 5V/μs (min)
  • High gain bandwidth: 15MHz (typ); 10MHz (min)
  • Wide power bandwidth: 120KHz
  • Low distortion: 0.002%
  • Low offset voltage: 0.3mV
  • Large phase margin: 60°

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

CMOS - CD4013, Dual D-Type Flip-Flop, 14-Pin DIP
The CD4013B device consists of two identical, independent data-type flip-flops. Each flip-flop has independent data, set, reset, and clock inputs and Q and Q outputs. These devices can be used for shift register applications, and, by connecting Q output to the data input, for counter and toggle applications. The logic level present at the D input is transferred to the Q output during the positive-going transition of the clock pulse.
