Overview
INTEGRATED CIRCUITS DATA SHEET TEA0676T Dual pre-amplifier and equalizer for reverse tape decks Product specification Supersedes data of 1996 Jun 20 File under Integrated Circuits, IC01 1997 Oct 07 Philips Semiconductors Product specification Dual pre-amplifier and equalizer for reverse tape decks FEATURES • Dual head pre-amplifiers • Reverse head switching • Equalization with electronically switched time constants • Output level like Dolby level of 387.
5 mV = 0 dB • Improved EMC behaviour.
GENERAL DESCRIPTION TEA0676T The TEA0676T 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 drivers with reverse heads.
The device will operate with power supplies in a range of 7.
6 to 12.
0 V.
The output overload level increases with the increase in supply voltage, so it is advisable to use a regulated power supply or a supply with a long time constant.
QUICK REFERENCE DATA SYMBOL VCC ICC S+N ------------N Vo (rms) PARAMETER supply voltage supply current signal plus noise-to-noise ratio output voltage (0 dB) (RMS value) VCC = 10 V unweighted RMS value gain internal = 40 dB; linear CONDITIONS MIN.
