The Sanyo Denki LA1245 is a monolithic linear integrated circuit designed as a high-performance AM electronic tuner. It incorporates a comprehensive set of functions required for AM tuning, including an RF amplifier, MIX, OSC with ALC, detection, IF amplifier, and AGC.
Key features include a stable local oscillation from LW to SW, facilitating multi-band use. The device provides an automatic search-stop signal, local oscillator buffer-output, and low-level local oscillation. It boasts excellent sensitivity with low-noise transistors in a cascode circuit, and a double-balanced differential MIX to prevent spurious radiation and IF interferences. The IC offers good S/N ratio and compensation for VCC fluctuation, allowing for minimal gain and distortion fluctuation.
The LA1245 is housed in a DIP20S package and operates within a temperature range of -20°C to +70°C. Its design facilitates electronic tuning systems and frequency representation, making it suitable for various AM radio applications.
