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 Philips TEA0677T is a monolithic bipolar integrated circuit intended for use in car radios. It functions as a dual pre-amplifier and equalizer with electronically switchable time constants (70 µs or 120 µs) and inputs for tape drives featuring reverse heads.
The device operates with power supplies ranging from 7.6 V to 12.0 V and is designed to replace the TEA0675T in low-cost car radios using the same PCB, allowing external components for Dolby B and music search features to be omitted.
