D.Module2.ADDA500K16
6-channel, 16 bit, 500 KSPS A/D and D/A Frontend
The D.Module2.ADDA500K16 is an A/D, D/A converter daughter card for the D.Module2 family of DSP Computer Modules. The main application areas are fast control loops, servo positioning, power-line monitoring, and automatic test equippment.
This daughter card is based on a 6-channel ADS8556 A/D converter and a DAC8822 D/A
converter. The ADC frontend simultaneously samples up to 6 single-ended inputs or
three differential inputs. The full-scale input range is programmable from ±1V to
±3V. (15V OEM option: ±1 to ±12.5V). The inputs are protected against
over-voltages up to 40V. Internal and external calibration options are provided.
Conversion start can be generated internally (programmable sampling frequency)
or driven by an external input. The D/A converters operate either synchronized
to the A/D converters or independently. The outputs are ±2.5V single-ended.
