We tested the analog part of the LF ELF receiver with our spin-off project 130485 (16-bit-ADC EEC/Gnublin-Module for Datalogger Applications, PCB 130485-1). The LF ELF receiver is a nice application for the little 16 bit ADC. Now the schematic can be reduced to the analog input amplifier, filter and power supply. The level shifter is placed on the ADC PCB.
