The INA128 and INA129 are low power, generalpurpose instrumentation amplifiers offering excellentaccuracy. The versatile 3-op amp design and small sizemake them ideal for a wide range of applications.Current-feedback input circuitry provides widebandwidth even at high gain (200kHz at G = 100).
Due to a lot of interest in the circuit of the color organ kit i decide to make a more simple circuit operating under 12 volts .
Please feel free to ask for definitions

cd4041ub quad true/complement buffer
The CD4041UB/CD4041UBC is a quad true/complementbuffer consisting of N- and P-channel enhancement modetransistors having low-channel resistance and high current(sourcing and sinking) capability. The CD4041 is intendedfor use as a buffer, line driver, or CMOS-to-TTL driver.All inputs are protected from static discharge by diodeclamps to VDDand VSS.
The 4N25 family is an industry standard single channelphototransistor coupler. This family includes the 4N25,4N26, 4N27, 4N28. Each optocoupler consists of galliumarsenide infrared LED and a silicon NPN phototransistor.

These 8-bit registers feature totem-pole 3-STATE outputsdesigned specifically for driving highly-capacitive or rela-tively low-impedance loads. The high-impedance state andincreased high-logic level drive provide these registers withthe capability of being connected directly to and driving thebus lines in a bus-organized system without need for inter-face or pull-up components. They are particularly attractivefor implementing buffer registers, I/O ports, bidirectional busdrivers, and working registers

4047 monostable multivibrator
The CD4047B is capable of operating in either themonostable or astable mode. It requires an external capac-itor (between pins 1 and 3) and an external resistor(between pins 2 and 3) to determine the output pulse widthin the monostable mode, and the output frequency in theastable mode.Astable operation is enabled by a high level on the astableinput or low level on the astable input. The output fre-quency (at 50% duty cycle) at Q and Q outputs is deter-mined by the timing components. A frequency twice that ofQ is available at the Oscillator Output; a 50% duty cycle isnot guaranteed.Monostable operation is obtained when the device is trig-gered by LOW-to-HIGH transition at + trigger input orHIGH-to-LOW transition at − trigger input. The device canbe retriggered by applying a simultaneous LOW-to-HIGHtransition to both the + trigger and retrigger inputs.A high level on Reset input resets the outputs Q to LOW, Qto HIGH.
