This I/O module is a high-end, low-noise analog module with an input resolution of 24 bits. Each analog input channel is equipped with its own dedicated DC-coupled Sigma-Delta A/D converter for sample rates up to 200 kSamples/s. Each converter integrates a 2-pole lowpass analog filter with software selectable cut-off frequency of either 40 kHz or 270 kHz.
Select this I/O module for precision voltage measurements, acquisition of audio signals, and other high dynamic-range signal measurements. Several IO109 modules can be synchronized to form a high channel count, high-resolution A/D subsystem. Synchronization can also be accomplished with analog output modules like the IO107 and IO108 to form a phase-locked I/O subsystem ideal for audio applications.
