Low Noise Geophone Differential Amplifier
Budget: $250 – $750 USD
The main objective of this project is to develop a noncommercial low cost, high quality, low noise geophone differential amplifier to provide signal for an off-the-shelf high precision AD/DA board ADS1256 DAC8552 AD/DA Raspberry Pi unit.
The work here is to develop a PCB Board design for the LNGDA module using the “CS3301A Geophone Low Noise, Programmable Gain Differential Amplifier” chip from the Cirrus Logic. Or a similar better performance chip.
The geophone is a generic low budget 4.5 Hz ~30 V/m/s product available commercially. The system response will be from 2 seconds to 100 Hz.
