KA358

The KA358 is a Dual High Impedance Differential Amplifier/Buffer Amplifier that eliminates the need for complex emitter follower or current source circuits. It is designed to allow a user to alternately double or halve the voltage on a signal output. The amplifier has an extremely low input bias current, which allows it to be used in various applications with minimal impact on performance. Additionally, the KA358 is capable of driving differential capacitive loads while providing excellent common-mode and differential-mode noise immunity.

The KA358 has two independent high-impedance differential amplifiers/buffer amplifier stages. The devices are made up of a matched pair of transistors and a resistor network, with each channel having a common-mode range of 15V. Each channel can reproduce signals over a wide range of frequencies, but this depends on the load presented to the amplifier and the overall input voltage. The amplifier is also able to handle high levels of external noise and has a wide range of gain adjustment and input bias current adjustment options.

The KA358 is often found in audio processing and instrumentation applications due to its high impedance and excellent performance characteristics. In the field of audio processing, the KA358 can be used to process high-frequency signals such as those in a guitar amplifier. It can also be used in high-end studio monitoring systems to adjust the level of various frequencies. In instrumentation applications, the KA358 can be used to provide an accurate, repeatable signal output for thermocouples and other temperature sensors. Other applications include industrial process monitoring and control systems, where the KA358 can be used to monitor and measure various parameters such as temperature, pressure, and voltage.

The KA358 operates on the principle of comparing the difference between two input signals and amplifying the output based on this difference. The input signals are sent through the amplifier and then compared to one another. The output of the amplifier is then calculated by taking the difference between the two signals, and then multiplying it by the gain set by the user. This output is then sent to the output terminals of the device, where it is then available for use. By setting the gain of the amplifier, the user can control the magnitude of the output signal they receive.

The KA358 is an ideal device for applications requiring a low distortion, repeatable, and stable output. Its high-impedance input and output stages provide excellent noise and interference immunity, and its wide gain range makes it suitable for many applications. Its circuit design gives it good temperature stability and reduces the need for external components. The KA358 is a reliable, high-performance device for instrumentation, industrial process monitoring and control applications.
