UA733CDR Integrated Circuits (ICs)

The UA733CDR is a linear amplifier that can be used in many different application fields. It’s been used to amplifiers audio signals, in radio broadcast equipment, for video amplification, and in various consumer electronic devices. The UA733CDR is a monolithic, single-stage circuit designed for low power video amplification and can be used with a variety of video signals such as NTSC and PAL. It has an excellent linear response across the entire frequency band and exhibits minimal distortion at high amplification levels.

Working Principle

The UA733CDR is an integrated circuit that consists of two transistors, an emitter-coupled amplifier, and a current-feedback amplifier. The current-feedback amplifier provides a high gain and fast response time, while the emitter-coupled amplifier provides low distortion and wide bandwidth. The circuit operates in class A mode, where current is supplied to the input stage of the amplifier and the output stage of the amplifier is biased to operate with a stationary working point. The output stage of the amplifier is also configured to be voltage-variable, where the voltage is varied by the input stage current. The output of the amplifier is then connected to the output device, where it amplifies the input signal.

The UA733CDR uses a wideband transformer to provide the high gain and fast response. The input of the transformer is connected to the input of the current-feedback amplifier and the output is connected to the output device. The transformer increases the gain by allowing it to match the impedance of the output device, which reduces distortion and improves the frequency response.

TheUA733CDR can be used to amplify both analog and digital video signals. It has a wide frequency response and is stable over a wide temperature range. In addition, it can drive high-impedance loads, making it suitable for amplifying signals in applications such as digital TV, satellite receivers, and video games.
