GENERAL DESCRIPTION
The TDA7088T is a bipolar integrated circuit for use in mono portable and pocket radios. It is used when a minimum of peripheral components (of small dimensions and low costs) is important. The circuit contains a frequency-locked-loop (FLL) system with an Intermediate Frequency (IF) of about 70kHz. Selectivity is achieved by active RC-filters. De-tuning related to the IF and too weak input signals is suppressed by the mute circuit.

FEATURES
• Equipped with all stages of a mono receiver from antenna to audio output
• Mute circuit
• Search tuning with a single varicap diode
• Mechanical tuning with integrating AFC
• AM application supported
• Power supply polarity protection
• Power supply voltage down to 1.8 V.
