In 1969, the first triple operational transconductance amplifier or OTA was introduced. The wide acceptance of this new circuit concept prompted the development of the single, highly linear operational transconductance amplifier, the CA3080. Because of its extremely linear transconductance characteristics with respect to amplifier bias current, the CA3080 gained wide acceptance as a gain control block. The CA3094 improved on the performance of the CA3080 through the addition of a pair of transistors; these transistors extended the current carrying capability to 300mA, peak. This new device, the CA3094, is useful in an extremely broad range of circuits in consumer and industrial applications; this paper describes only a few of the many consumer applications.

In the past there has been several approaches to the solid state horizontal deflection of magnetically deflected picture tubes. Some of the most recent circuitshave been based on the wellestablished trace-driven principle in combination with some kind of converter power-supply (1). Others have been based on the retrace-driven principle, and here the application of silicon controlled rectifiers have been most interesting (2).

Since RCA introduced the internal pole piece gun in the 700 picture tube in 1954, dynamic convergence of the individual beams has been the standard of the industry. With the 900 precision in-line color picture tube assembly, RCA introduces a totally new concept in color television display system utilizing an advanced design of the electron gun, the deflection yoke, and the picture tube to achieve superior performance in a simplified inherently lower-cost system. The combination of a precision unitized close-spaced in-line gun and a line-focus type PST ( precision static toroid) deflection yoke makes practical the first inherent self-converging color system. Convergence equivalent or superior to that of present commercial receivers is achieved without the use of any dynamic convergence correction or circuitry.

Are heatsinks really needed in the red-green-blue video amplifier? Their cost is appreciable. In large-volume consumer production, engineering effort to eliminate heatsinks is well worthwhile. This effort may make use of computer aid. In particular, computer programs having statistical analysis routines may be applied to power dissipation levels, thus providing greater information about transistor junction temperatures.

Recently several component manufacturers have introduced to the market a computer tuning radio which will tune in any selected station. Due to the cost of these systems they can only be offered in the top of the line. In my paper I would like to introduce a system which offers a greatly simplified approach to the problem of computer tuning.

The device incorporates such features as high current capability, temperature shut down and short circuit protection. It also offers a choice of operation over a wide range of output loads and supply voltages. Simple external circuitry and minimal circuit components make this IC an outstanding candidate for low to medium power audio systems, high power audio driver, servo motor driver, low voltage high current adjustable power supply and numerous thick film applications.

The advent of cablecasting has brought about renewed interest in the possiblities for new and improved performance in color television systems. The closed circuit environment, new technology for wide-bandwidths, new large area displays, and better signal transmission systems make it desirable to obtain the best possible performance from the NTSC system that is now serving very well for broadcast over-the-air transmissions.

A new dimension has been added to monolithic integrated circuit (IC) voltage regulators. A combination of circuit, device and processing innovations has led to the development of the ?A7800 series of 3-lead, 20-watt voltage regulators which feature output current capability in excess of 1A, low noise, and excellent regulation. They are available in fixed output voltage options covering the range of 5V to 30V using a built-in internal resistor matrix.
