UTC TDA7088

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


Application

*Mechanical tuning ; this is possible with or
 without integrating AFC circuit
*Electrical tuning; this is realized by one
 directional (band-up) search tuning facility,
 including RESET to the lower-band limit.

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. Detuning related to the IF and  too weak input signals is suppressed by the mute circuit.
