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 TEA0677T 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.
