TEA5551T Overview
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 plete AM part and dual AF amplifier with low quiescent current. The AF part has low radiation (HF noise) and good overdrive performance.
TEA5551T Key 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
TEA5551T Applications
- Low voltage operation (VS = 1.8 V to 4.5 V)
