NF HSA 42052 High-Speed Bipolar Amplifier

The NF HSA 42052 is a high-voltage bipolar amplifier designed for applications requiring speed, wide frequency range and high power capacity. With a frequency range of DC to 500 kHz and a maximum output voltage of 300 Vp-p, this amplifier is ideal for research and testing of piezoelectric actuators, magnetic materials, medical equipment and electric vehicle components.

The four-quadrant operation allows the amplifier to both supply and absorb voltage, which is essential for capacitive and inductive loads such as coils, transformers and piezo elements. The low output impedance ensures stable and accurate signal reproduction even with fast circuits and complex load requirements.

With a slew rate of 450 V/µs, the HSA 42052 can handle fast signal transitions without significant distortion. The maximum output current of 5.66 Ap-p enables powerful load testing at high frequencies. The gain is adjustable at ×1, ×20, ×40 and ×100, with variable fine adjustment between ×1 and ×3. This provides flexibility in adapting the output signals to different test scenarios.

The built-in DC bias adjustment to ±150 V allows a constant DC voltage component to be added to the output signal. This allows the amplifier to be adapted to specific applications where a shifted output signal is required. Furthermore, the HSA 42052 features output polarity switching, which allows direct inversion of the signal phase.

For optimal protection, the amplifier is equipped with overload, overvoltage and temperature monitoring, as well as internal fault detection. This increases reliability even in intense test environments.

The four-quadrant operation ensures that the amplifier remains stable when driving capacitive loads such as piezoelectric actuators and multilayer ceramic capacitors (MLCCs), as well as inductive loads such as coils and transformers. This makes the HSA 42052 suitable for research and development in automotive, material characterization and semiconductor manufacturing.
