DT9821 and DT9822

The DT9821 and DT9822 are high resolution USB data acquisition (DAQ) modules offering four 24-bit A/D converters for applications that require the highest level of accuracy. The channels are able to start/stop independently of each other, allowing individual channels to be added or removed from the scan list while the ADC is running to support industry standard time base independence. The DT9822 features two DC-level analog outputs, with resolution of 16 bits with ±5V range.

Key Features:

• Four separate 24-bit A/D converters
• Time base independent channels
• Variable resolution is set based on sample rate: 6.25 S/s to 960 S/s
• 16-bit analog output (DT9822)
• 16 digital TTL input/output signals (8 in, 8 out)
• External start/stop control lines for each A/D converter.
• Simultaneous subsystem supported to write/read from all subsystems independently.
• 500V isolation prevents ground loops and protects your computer.
• True plug-and-play: one cable supplies power and connections to the USB module, easy external connections, and hot-swapping capability
• Software and drivers compatible with Windows XP/Vista/7

The DT9821 and DT9822 are not recommended for new applications. Please consider the DT9824 as an alternative solution.
