ProDAQ 3416 16-Channel 24-bit Sigma-Delta Function Card

• 16 Channel Differential Input Sigma-Delta ADC
• 24-bit Resolution, Simultaneous Sampling
• 1 Sample/sec to 1 kSamples/sec Output Data Rate
• Programmable Gain 1 to 2000 per Channel
• On-board FIFO Memory
• Synchronized Multi-card Acquisition

The ProDAQ 3416 ADC Function Card contains sixteen Sigma-Delta Analog-to-Digital Converters, each equipped with its own filter and independently programmable gain stage with differential inputs. The gain is programmable from 1 to 2000, providing the user with voltage ranges from ±10 V down to to ±5 mV.

All channels are sampled simultaneously. The output data rate can be set between 1 Sample/s and 10 kSamples/s (-BA version) resp. 1 Sample/sec to 1 kSample/sec (-AA version) with a resolution of 0.01 Samples/sec. In addition the ProDAQ 3416 function cards can be synchronized with each other or with other ProDAQ function cards like for example the ProDAQ 3424 ADC function card or the ProDAQ 3808 Counter/Timer function card via the VXIbus trigger lines or the trigger lines on the front panel connector.

The voltage from the ProDAQ 3202 Programmable Voltage Reference Card can be switched directly to the input of the gain stage for calibration "on-the-fly" or self test purposes. The achievable absolute accuracy is better than ±(20 + 600/gain) µV, or typical 0.0012 % FSR for a gain of 1.

The ProDAQ 3416 ADC Function Card is supplied with VXIplug&play drivers, that can be used with all popular software packages. The driver automatically detects and initializes all the function cards installed in one of the ProDAQ motherboard modules, removing any possibility of configuration errors.
