Overview
INTEGRATED CIRCUITS DATA SHEET TEA0677T Dual pre-amplifier and equalizer for reverse tape decks Product specification File under Integrated Circuits, IC01 August 1993 Philips Semiconductors Product specification Dual pre-amplifier and equalizer for reverse tape decks FEATURES • Head pre-amplifiers • Reverse head switching • Equalization with electronically switched time constants • 0 dB = 387.
5 mV • Pin compatible to TEA0675 Dolby B, music search IC.
GENERAL DESCRIPTION TEA0677T The TEA0677T is a monolithic bipolar integrated circuit intended for applications in car radios.
It includes head and equalization amplifiers with electronically switchable time constants.
Furthermore it includes electronically switchable inputs for tape drives with reverse heads.
The device is intended to replace the regular TEA0675T in low-cost car radios using the same PCB.
External components that are necessary for Dolby B and music search features can be omitted.
The device will operate with power supplies in the range of 7.
6 V to 12.
0 V, output overload level increasing with increase in supply voltage.
Current drain varies with supply voltage, so it is advisable to use a regulated power supply or a supply with a long time constant.
