The TEA5711T2TM is a single chip radio integrated circuit designed by ST-Ericsson Inc. (now part of STMicroelectronics) for AM/FM portable radios. It's a complete solution integrating most of the functions required for a radio receiver, minimizing the need for external components.

Applications

• Portable AM/FM radios
• Clock radios
• Personal stereos
• Automotive radio systems (basic models)

Features

• Complete AM/FM radio receiver: Integrates AM and FM front-end, IF amplification, demodulation, and audio amplification.
• Low current consumption: Optimized for battery-powered portable applications.
• Minimum external components: Reduces the BOM (Bill of Materials) cost and simplifies PCB design.
• Alignment-free FM demodulator: No manual alignment needed during manufacturing.
• Electronic Volume Control: Offers precise volume adjustment via a DC control voltage.
• Stereo decoder: (FM Mode) Integrated stereo decoder for stereo FM reception.

Benefits

• Cost-effective radio solution: Minimizes component count and simplifies manufacturing.
• Extended battery life: Low power consumption extends the operating time of portable radios.
• Easy design and manufacturing: Reduced component count and alignment-free demodulator simplify the design and manufacturing processes.
• High-quality audio: Integrated audio amplifier delivers clear and powerful audio output.

Additional Details

The TEA5711T2TM is typically packaged in a small outline package (SOP). The integration of both AM and FM functionality in a single chip makes it a very compact solution. The electronic volume control allows for precise adjustment without mechanical potentiometers, enhancing reliability. The device operates on a single power supply voltage (typically 3V). The TEA5711T2TM is designed for basic radio functionality and may not include advanced features found in more complex radio receiver chips. The frequency ranges supported by the AM/FM front-end are designed to meet global broadcasting standards.
