Linear amplifiers are electronic devices used to amplify signals from small to large scale resulting in a larger output signal than the input. The HA5351IBZ is a hybrid linear amplifier designed specifically for instrumentation, operational amplifiers (op amps), and buffer amplifiers. This amplifier is part of the Hualon range and offers excellent drive power, low distortion, and high voltage capability.

The HA5351IBZ has a supply voltage range of 6V to 32V, an operating temperature range of -25° to +85°C, and an output power of up to 16W. It also has a very low distortion level, typically of 0.03%. The HA5351IBZ also has a high slew rate at 49V/μs and low quiescent power consumption of 2.2W.

The HA5351IBZ offers very good performance in audio applications. The amplifier boasts a 5kHz to 200kHz bandwith for a typical audio frequency range. The amplifier can reach levels up to 10Vpp for higher levels of performance. The HA5351IBZ has a low output impedance of 1Ω which prevents any significant losses occurring in the output stage due to impedance mismatch. The high slew rate helps to minimise noise at high frequencies which can often be a problem with audio frequencies.

When used in op amp applications, the HA5351IBZ can be used to perform low noise precision amplification. At very high gains, the amplifier can perform gain setting with excellent dynamic range, high accuracy and low noise. The low output impedance ensures that very low noise levels are maintained when boosting signals.

The HA5351IBZ is also well suited to buffer amplifier applications. As this type of amplifier is designed to minimise loading due to their high input impedance and low output impedance, the HA5351IBZ is the ideal choice. The amplifier features a high input impedance of 90kΩ, which ensures high fidelity and prevents any significant loading of the input signal. The low output impedance also prevents any losses occurring due to high impedance mismatches.

The working principle of the HA5351IBZ is simple. An incoming signal is received by the amplifier, amplified and then output. The amplifier consists of three stages; the pre-amplifier, the primary amplifier and the feedback loop. The first stage, the pre-amplifier, takes the incoming signal and boosts it for further processing. This is followed by the primary amplifier stage, which provides the majority of the gain. The feedback loop is the last stage and is used to regulate the level of the output and ensure it is within the proper voltage/current range.

Overall, the HA5351IBZ is an excellent choice of linear amplifier for instrumentation, op amp, and buffer amplifier applications. Its excellent performance, low distortion, and high voltage capabilities make it ideal for a wide range of applications. The low output impedance helps to maintain a low noise level, while the high input impedance helps to prevent loading of the input signal. The various stages of the amplifier help to boost the signal and regulate output to ensure accuracy and reliability.
