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.

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.

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 70 khz. selectivity is achieved by
active rc-filters. de-tuning related to the if and too weak
input signals is suppressed by the mute circuit.
