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.
