Description
The ispPAC
System Programmable (ISP) analog integrated cir-
cuits. It is digitally con
fi
gured via SRAM and utilizes
E
CMOS memory for non-volatile storage of its con
fi
gu-
ration. The
fl
exibility of ISP enables programming, veri
fi
-
cation and unlimited recon
fi
guration, directly on the
printed circuit board.
30 is a member of the Lattice family of In-
2
The ispPAC30 is a complete front end solution for data
acquisition applications using 10 to 12-bit ADC's. It pro-
vides multiple single-ended or differential signal inputs,
multiplexing, precision gain, offset adjustment,
fi
ltering,
and comparison functionality. It also has complete
routability of inputs or outputs to any input cell and then
from any input cell to either summing node of the two
output ampli
fi
ers. Designers con
fi
gure the ispPAC30
and verify its performance using PAC-Designer
easy to use, Microsoft Windows
ment tool. Device programming is supported using PC
parallel port I/O operations.
