Low Power Low Noise Hydrophone Preamplifier

BII-1060 Series   Low Power Low Noise Hydrophone Preamplifier

Technical notes
The cable has adverse effects on the signal quality in high frequency range. The longer the cable is, the worse the adverse effects is. If you use long cable in your project, you may specify customized output impedance of BII's preamplifiers to match cable impedance and the DAQ input impedance, for example, customized 50 ohms output impedance of BII preamplifier for 50 ohms RG58 coax of DAQ system.

Specification

How to choose preamplifier? If frequency of interest covers low frequency range up to 10kHz, a preamplifier with low current noise should be used. If frequency of interest only cover high frequency range greater than 10kHz, a preamplifier with low voltage noise should be used.
Rectangular PCB LxWxH = Length x Width x Height. Round PCB ΦDxH = Diameter x Height. HPF: High Pass Filter; BPF: Band Pass Filter.
SE: Single-ended; DF: Differential.
