Dual pre-amplifier and equalizer for

reverse tape decks

Product specification

TEA0676T

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

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.
