D.Module2.ADDA500K16

The D.Module2.ADDA500K16 is based on the Texas Instruments data converters ADS8556 and DAC8822. The analog front end digitizes up to 6 single-ended or 3 differential voltage inputs with 16-bit resolution and sampling rates up to 500ksps. The two DAC outputs also deliver 16-bit resolution. Input range and sampling frequency are user-programmable.

Key Features

Simultaneous Sampling up to 500kS/s
6 single-ended / 3 differential inputs
2 outputs
16-bit resolution
low latency
input range 2.5V (option: 10V)
multiplexers for gain and offset calibration

Applications

The D.Module2.ADDA500K16 allows to simultaneously digitize voltage and current in 3-phase systems, e.g. AC induction and brushless DC motor control, and power line monitoring. The high sampling frequency guarantees excellect spectral resolution and short latencies in servo control loops. High resolution and superb static and dynamic characteristics make this module equally well suited for general measurements tasks.
