The TEA0675 is a bipolar integrated circuit that provides two channels of Dolby B noise reduction for playback applications in car radios. It includes head and equalization amplifiers with electronically switchable time constants. Furthermore it includes electronically switchable inputs for tape drivers with reverse heads.
This TEA0675 device also detects pauses of music in the Automatic Music Search (AMS) scan mode, for applications with an intelligent controlled tape driver, or AMS-latch mode, for applications with a simple controlled tape driver. For both modes, the delay time can be fixed externally by a resistor. The device operates with power supplies in the range of 7.6 to 12 V, output overload level increasing with increase in supply voltage.
Current drain varies with the following variables: supply voltage noise reduction on/off AMS on/off. Because of this current drain variation it is advisable to use a regulated power supply or a supply with a long time constant.
