TEA5551T - NXP

TEA5551T 1-chip AM radio

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 .
