INTEGRATED CIRCUITS DATA SHEET TEA5551T 1-chip AM radio October 1990 Product specification File under Integrated Circuits, IC01 Philips Semiconductors Product specification 1-chip AM radio TEA5551T GENERAL DESCRIPTION The TEA5551T is a 1-chip monolithic integrated radio circuit which is designed for use as a pocket receiver with headphones in a supply voltage range (VS) of 1.8 V to 4.5 V. The circuit consists of a complete AM part and dual AF amplifier with low quiescent current. The AF part has low radiation (HF noise) and good overdrive performance. The dual AF amplifier makes the device suitable for operation in an AM/FM stereo receiver with or without stereo cassette player. The IC has a 1-pin switch for AM or other applications. Features • Low voltage operation (VS =
