TEA0676 Datasheet | NXP Semiconductors

FEATURES - Dual head pre-amplifiers - Reverse head switching - Equalization with electronically switched time constants - Output level like Dolby level of 387.5 m V = 0 d B - 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.
