PX453S
PXI 12-Bit ADC

The PX453S is a 16 or 32 channel
12-bit A/D converter that provides
autonomous signal conversion using
an on-board DSP to provide a
programmable scan rate, gain/offset
compensation, and storage of
conversion results. The common-
mode voltage inputs are optically
coupled and have programmable
input ranges. Each input has a
1KHz anti-aliasing filter and a
programmable moving average
filter. Stored data is automatically
corrected with stored calibration
data.
