KA2213 single chip sound recorder or reproducer integrated circuit diagram

KA2213 is a single-chip record and playback integrated circuit produced by Samsung in South Korea. It is utilized in audio recording and playback devices. The internal circuit block diagram and pin functions of the KA2213 include a record and playback preamplifier, a power amplifier circuit, an automatic gain control circuit (ALC), and a ripple filter circuit. The KA2213 is housed in a 14-pin dual in-line package with cooling ribs. The integrated circuit's pin functions and specifications are detailed in the accompanying chart. The typical application circuit for the KA2213 is illustrated in the figure, which does not include a flux imbalance circuit. Switches SW1 to SW6 function as record and playback controls, with their graphical positions indicating the sound-reproducing state.

The KA2213 integrated circuit is designed for efficient audio recording and playback applications, making it suitable for various audio devices such as cassette recorders, mini-disc players, and other audio equipment. The internal architecture is optimized for high fidelity, featuring a record and playback preamplifier that boosts audio signals to appropriate levels for processing. The automatic gain control (ALC) circuitry ensures consistent output levels by adjusting the gain based on the input signal strength, which is essential for maintaining audio clarity during playback and recording.

The power amplifier circuit within the KA2213 is engineered to drive speakers or headphones directly, providing sufficient power output while minimizing distortion. The ripple filter circuit serves to reduce noise and interference, enhancing the overall audio quality. The 14-pin dual in-line package design facilitates easy integration into existing electronic systems, while the cooling ribs help dissipate heat generated during operation, ensuring reliable performance.

In practical applications, the KA2213 can be connected to various input sources, such as microphones or line-level audio signals, and can interface seamlessly with other components in a sound system. The switches SW1 to SW6 allow users to easily toggle between recording and playback modes, providing intuitive control over the device's functionality. The absence of a flux imbalance circuit in the typical application diagram indicates a simplified design, focusing on essential features for standard audio applications. This design approach makes the KA2213 a versatile choice for engineers and designers seeking reliable audio performance in their projects.KA2213 is a single chip record and play back integrated circuit which is produced by South Korea`s Samung, it is used in recorder and unit audio. 1, KA2213 internal circuit block diagram and pin function KA2213 internal block contains a record and play back preamplifier, a power amplifier circuit, a automatically gain control circuit(ALC)and ripple filter circuit.
