APPLICATIONS
DESCRIPTION
The QF4A512 Programmable Signal Converter is a 4-channel,
signal conditioner and signal converter. Each channel can be
individually programmed for the gain, anti-aliasing filter cutoff
frequency, A-to-D sampling frequency, and unique filter
requirements. This is accomplished with 4 separate high-
precision 512-tap FIR filters.
Quickfilter Pro software has been created for rapid device
configuration
unattainable with analog components.
