PVA560 Low-Noise Voltage Preamplifier | DC to 1 MHz | 3 nV/√Hz Input Noise | Gain 1–50,000 | Battery/AC Powered

The PVA560 is a high-performance, ultra-low-noise voltage preamplifier designed for amplifying weak low-frequency signals. With a noise density of just 3 nV/√Hz, DC to 1 MHz bandwidth, and variable gain from 1 to 50,000 (1-2-5 sequence), it is ideal for cryogenics, low-frequency noise measurements, sensor signal conditioning, photodetection, audio, and vibration applications.
