Product specification
Dual pre-amplifier and equalizer for
reverse tape decks
TEA0677T
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
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.
