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.

Hello, Thanks for posting the project. I am an Electrical Engineer with 30 years’ experience of Customized Product Development for Instrumentation and Control applications. I am based in Kolkata (India) and running a business in the name of "Zetek Systems". I have a good hardware setup and a team for fabrication and testing. Your requirement is four ch. LNGDA. CS3301A is a two channel multiplexed amplifier. So you can do with only two such chips. But I suggest to use four CS3301A without multiplexing to improve the overall AD conversion speed of the system. For this project we can discuss more detailed specification (including power supply), deliverables and milestones through chat. Looking forward to your valued reply. Regards - Debasis Basu

Hi there, I'm Peter I am very experienced with the design, simulation and construction of Low frequency circuitry, be it amplifiers, or their corresponding ADCs and DACs, I understand the bits and bobs involved in their construction, and i would really love to work on your project. I design analysis circuitry in my spare time for my research purposes so I have gained the experience over time. Please feel free to go through my previous works, portfolio and reviews, I do a lot more than circuitry of this class and kind and I would love to really work on your project and give you the best experience as I have done others. I would really love to hear from you, you will love my work. Please leave a message Thanks Peter.
