The IO113-20 I/O module is a precision 20-bit analog module with eight simultaneously clocked output channels and Simulink® driver blocks.
The outputs can be clocked at rates of up to 500 KSPS per channel and are supported by a 256K-Sample FIFO data buffer. Both continuous and burst clocking modes are supported, and voltage ranges are software-selectable as ±10 V and ±5 V or ±5 V and ±2.5 V (See technical specifications).
Each analog output channel implements a weighted-DAC R-2R configuration, which has no minimum clocking rate and decreases latency.
The outputs can be software-configured either for single-ended operation or for 3-wire differential operation.
On-demand autocalibration determines and applies error correction for all output channels, and the eight bidirectional digital I/O lines are programmable as inputs or outputs.
