SA1135
AM RADIO IC FOR DIGITAL TUNING SYSTEM
DESCRIPTION
The SA1135 is a high-performance AM electronic tuner IC. It is
especially suited for use in car radio and home stereo applications.
FEATURES
DIP-20-300-2.54
* Excellent cross modulation characteristics: Meets the requirements
for preventing not only adjacent-channel interference but also
interference caused by all channels within broadcast band.
* Narrow-band signal meter output: Usable as auto search stop signal.
SOP-20-300-1.27
* Local oscillation buffer output: Facilitates designing of electronic
tuner system, etc.
* Good characteristics at high input: 130 dBµ input fm = 400 Hz 80% ORDERING INFORMATION
mod THD = 0.4% typ.
* Low noise: Good S/N at medium input (56 dB typ.)
