Analogue Front End design -- 2
Budget: $25 – $60 USD
We have a requirement to design schematics and preliminary PCB layout for an analogue front end for a data logger system.
Specification as follows:
* 8 differential or 16 single ended input channels (configurable)
* SPI interface to ADC
* up to 128x PGA
* Bipolar input capable (+/- 1.8V min)
* Able to measure thermocouples and other general high sensitivity inputs
We have tentatively selected the AD7124-8 as the ADC for this task, however if there are better options available we are open to suggestions. Work will include power architecture/design for bipolar supplies and any necessary references and circuit protection.
