KA2101 TV Sound IF Amplifier DIP-14

KA2101 TV Sound IF Amplifier DIP-14

The KA2101 TV Sound IF Amplifier DIP-14 is a versatile, monolithic integrated circuit designed to enhance sound processing in television systems. It integrates multiple functions, including IF amplification, IF limiting, detection, electronic attenuation, audio amplification, and audio driver capabilities, making it an all-in-one solution for TV sound systems. With its high sensitivity (200μV limiting at 4.5MHz) and excellent AM rejection across various frequencies (4.5MHz, 5.5MHz, 6.0MHz, 6.5MHz), the KA2101 ensures clear, interference-free audio output.

The built-in electronic attenuator replaces traditional DC volume controls, providing more precise and efficient volume adjustment. Additionally, the internal Zener diode regulated supply ensures stable operation, while the differential peak detector requires only one single tuned coil, simplifying circuit design. Packaged in a 14-pin DIP (Dual In-line Package), the KA2101 operates reliably within a temperature range of -20°C to +75°C, making it suitable for a wide range of electronic equipment.
