KA2411 Description

Short technical summary and product information.

The KA2411 is a bipolar integrated circuit designed for telephone tone ringer applications. It consists of an output amplifier, two oscillators, and a power supply control circuit. This device offers low current drain and adjustable two-tone frequencies, making it suitable for telephone bell replacement, extension tone ringer modules, and various alerting devices.

The KA2411 operates with a DC supply voltage up to 36V and has a power dissipation of 450mW. Its operating ambient temperature range is -25°C to +75°C. The integrated circuit is housed in an 8-pin DIP plastic package and is designed for through-hole mounting.

Key electrical characteristics include a supply initiation voltage typically between 17V and 21V, and a sustaining voltage typically between 9.7V and 12V. The oscillator frequencies can be adjusted externally using resistors and capacitors, with typical low frequencies around 1011Hz and high frequencies around 512Hz and 640Hz.

This component is designed to prevent false triggering and rotary dial "chirps" due to its hysteresis circuit. The KA2411 also allows for reduced supply initiation current, enhancing its efficiency in various alerting systems.
