IO113-18: 18-bit Analog Output Module

18-bit analog module with 8 single-ended or 3-wire differential output channels and Simulink driver blocks

The IO113-18 I/O module is a precision 18-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, ±5 V or ±2.5 V. 

Each analog output channel implements a weighted-DAC R-2R configuration, which minimizes latency and has no minimum clocking rate. 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 eight bidirectional digital I/O lines can be programmed as inputs or outputs.
