Analog-to-Digital Function Modules

Description

AD1, AD2 and AD3 Analog-to-Digital function modules are 12- channel A/D modules with 24-bit Sigma-Delta A/D converters for each individual channel with maximum programmable expected full-scale range inputs of 10, 100V, and ±25 mA (current only) respectively. The A/D converters provide simultaneous, programmable sample rates of up to 256 kHz.

 

Each A/D module provides field programmable input range and gain for each channel. The ability to set lower than expected, full-scale voltage gain ranges assures the use of the full resolution. Each channel includes an anti-aliasing filter with an inherent digital “brick wall” filter and a digital second-order IIR low-pass filter with a programmable breakpoint that enables users to field-adjust the filtering for each channel. All channels have continuous background Built-In-Test. The modules also include extended A/D FIFO buffering capabilities for greater storage/management of the incoming signal samples for post processing applications. Programmable FIFO buffer thresholds maximize data flow control. Incremental relative time-stamping between samples is also provided as a programmable option.
