The TEA5760UK1S24TM is a single-chip radio integrated circuit for FM portable radios from ST-Ericsson. This integrated circuit offers high integration and low power consumption, making it suitable for battery-operated devices. It integrates the functions of an FM front-end, IF processing, and stereo decoder into a single chip.

Applications

• Portable FM radios
• Clock radios
• Personal stereos
• Car radios (low-end)

Features

• High sensitivity FM receiver
• Low power consumption
• Fully integrated FM IF processing
• Stereo decoder with noise blanking
• Automatic Gain Control (AGC)
• Automatic Frequency Control (AFC)
• Soft mute function
• I²C-bus control interface

Benefits

• Reduced component count, leading to smaller and more cost-effective radio designs.
• Extended battery life due to low power consumption.
• Improved reception quality with AGC and AFC features.

Additional Details

The TEA5760UK1S24TM requires minimal external components, which simplifies the design process. The I²C-bus interface allows for easy control of the receiver parameters, such as frequency tuning, volume control, and mute function. The integrated stereo decoder provides high-quality audio output, and the noise blanking feature helps to reduce unwanted noise and interference. The device operates from a single supply voltage, making it suitable for battery-powered applications.

The AGC ensures consistent audio output levels, even with varying signal strengths. The AFC keeps the receiver tuned to the correct frequency, even with slight drifts in the oscillator. These features contribute to a stable and reliable radio performance.
