The Spartan
consisting of a programmable scaling pre-amplifier and an analog-to-digital converter
(ADC), as shown in
The analog capture circuit consists of a Linear Technology LTC6912-1 programmable pre-
amplifier that scales the incoming analog signal on header J7 (see
of pre-amplifier connects to a Linear Technology LTC1407A-1 ADC. Both the pre-amplifier
and the ADC are serially programmed or controlled by the FPGA.
