High-resolution 24-bit sigma-delta analog module with 12 differential analog
This I/O module is a high-end, low-noise analog module with 12 differential input
channels and a resolution of 24 bits. Each of the 12 input channels has its
dedicated DC-coupled Sigma-Delta A/D converter with an update time of 5 µs.
Each converter integrates a 2-pole lowpass analog filter with a software selectable
cut-off frequency of either 40 kHz or 270 kHz.
Select this I/O module for precise voltage measurements, the acquisition of audio
signals, and other high dynamic-range signal measurements. Several IO109 I/O modules
can be synchronized to form a high-channel-count, high-resolution A/D subsystem.
Synchronization can also be accomplished with analog output modules such as the
IO107 and IO108 I/O modules to form a phase-locked I/O subsystem ideal for audio
