TEA5551T

INTEGRATED CIRCUITS DATA SHEET TEA5551T 1-chip AM radio Product specification File under Integrated Circuits, IC01 October 1990 Philips Semiconductors Product specification 1-chip AM radio GENERAL DESCRIPTION TEA5551T 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 = 1.8 V to 4.5 V) Low current consumption (Itot = 5 mA at VS = 3 V) All pins provided with ESD protection AM part High sensitivity (Vi = 1.5 µV for Vo = 10 mV) Good IF suppression Good signal handling (Vi(max) = 80 mV) Switch for AM or other applications Short waveband (> 40 MHz) AF part A fixed integrated gain of 32 dB Few external components required Very low quiescent current Low HF radiation and good AF overdrive performance 0 to 20 kHz limited frequency response 25 mW per channel output power in 32 Ω October 1990 2 Philips Semiconductors Product specification 1-chip AM radio QUICK REFERENCE DATA (at Tamb = 25 °C) PARAMETER Supply voltage Supply current AM part RF sensiti...
