Features.
Implemented in plastic small-size 24-pin
SSOP-case with external lead pitch 0,65mm;
- supply voltage 4.5 to 5.5V;
- consumption current 42 to 58 mkA;
- operation temperature range - 20ºC
≤
Tamb
≤
80ºС;
- used frequency channels correspond to
european standards with the following radio-
frequency ranges:
48.25 MHz to 168.25 MHz;
175.25 MHz to 447.25 MHz;
455.25 MHz to 855.25 MHz
- when using the corresponding external
interconnection circuit, they are suitable for
construction of all-channel tuners NTSC (USA
and Japan).
- allows the designer to make economic and
small-size 3-bands tuner;
Using ILA5737D time of tuner fabrication may be
considerably reduced. Temperature compensation
of reference voltage.
