DESCRIPTION
The UTC TDA7088 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 1.8V
