FM RECEIVER CIRCUIT FOR
BATTERY SUPPLY
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
SOP-16
APPLICATIONS
*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.
