8-input 16-bit Analog Acquistion Module
The MADC-1816 offers simultaneously sampling A/D architecture with 8 single-ended or 4 differential analog input channels.
All channel features programmable gain 1 or 2 and can program to handle analog input with a single-ended or differential configuration.
The acquisition can be started by the host or by an on-board sequencer that uses a channel list to specify which channel to acquire. A local 8Kx16 but dual ported SRAM stores the acquisition data. Memory pointers can be selected t limit the number of scans gathered, as well as the control of interrupt generation.
The 16-bit A/D converters can provide a global acquisition and conversion time of ≤5µsec per sample per channel.
The board offers a programmable digital filter:
- Using ±5 V range, the −3 dB frequency is typically 15 kHz.
- With the ±10 V range, the −3 dB frequency is typically 23 kHz.
Applications
This board is optimally suited for the following application domains:
- Process control
- Industrial control
- Precision instrumentation
- Data acquisition systems (DAS)
- Multi-axis positioning systems
Software
Both Linux and Windows drivers are available.
