Low noise, 24-bit resolution, low phase distortion and multi-board synchronization make the PMC-24DSI12 board ideal for state-of-the-art sonar and noise monitoring applications. The 12-channel 24DSI12 analog input board provides a high-density 24-bit analog input resources on a several expansion board. Optimized for flexibility and performance, the board is ideal for a wide variety of applications, ranging from simple precision voltage measurements, to the analysis of complex audio signals and waveforms.

Each of the 12 delta-sigma analog input channels can be controlled by any one of two independent sample clocks, and multiple channels can be harmonically locked together. A/D conversions on multiple boards can be synchronized and phase-locked. Input bandwidth is from DC to 80kHz. Sample rates are adjustable from 2KSPS to 200KSPS, and the input range is software selectable as ±2.5V, ±5V or ±10V. Internal autocalibration networks permit periodic calibration to be performed without removing the board from the system.
